Equilibrium Constant of Electrochemical Cell Reaction

Equilibrium Constant of Electrochemical Cell Reaction The equilibrium constant of an electrochemical cells redox reaction can be calculated using the Nernst equation and the relationship between standard cell potential and free energy. This example problem shows how to find the equilibrium constant of a cells redox reaction. Problem The following two half-reactions are used to form an electrochemical cell:Oxidation:SO2(g) 2 H20(â„“) → SO4-(aq) 4 H(aq) 2 e-  Ã‚  E °ox -0.20 VReduction:Cr2O72-(aq) 14 H(aq) 6 e- → 2 Cr3(aq) 7 H2O(â„“)  Ã‚  E °red 1.33 VWhat is the equilibrium constant of the combined cell reaction at 25 C? Solution Step 1: Combine and balance the two half-reactions. The oxidation half-reaction produces 2 electrons and the reduction half-reaction needs 6 electrons. To balance the charge, the oxidation reaction must be multiplied by a factor of 3.3 SO2(g) 6 H20(â„“) → 3 SO4-(aq) 12 H(aq) 6 e- Cr2O72-(aq) 14 H(aq) 6 e- → 2 Cr3(aq) 7 H2O(â„“)3 SO2(g) Cr2O72-(aq) 2 H(aq) → 3 SO4-(aq) 2 Cr3(aq) H2O(â„“)By balancing the equation, we now know the total number of electrons exchanged in the reaction. This reaction exchanged six electrons. Step 2: Calculate the cell potential.This electrochemical cell EMF example problem shows how to calculate cell potential of a cell from standard reduction potentials.**E °cell E °ox E °redE °cell -0.20 V 1.33 VE °cell 1.13 VStep 3: Find the equilibrium constant, K.When a reaction is at equilibrium, the change in free energy is equal to zero. The change in free energy of an electrochemical cell is related to the cell potential of the equation:ΔG -nFEcellwhereΔG is the free energy of the reactionn is the number of moles of electrons exchanged in the reactionF is Faradays constant (96484.56 C/mol)E is the cell potential. The cell potential and free energy example shows how to calculate free energy of a redox reaction.If ΔG 0:, solve for Ecell0 -nFEcellEcell 0 VThis means, at equilibrium, the potential of the cell is zero. The reaction progresses forward and backward at the same rate, meaning there is no net electron flow. With no electron flow, there is no current and the potential is equal to zero.Now there is enough information known to use the Nernst equation to find the equilibrium constant.The Nernst equation is:Ecell E °cell - (RT/nF) x log10QwhereEcell is the cell potentialE °cell refers to standard cell potentialR is the gas constant (8.3145 J/mol ·K)T is the absolute temperaturen is the number of moles of electrons transferred by the cells reactionF is Faradays constant (96484.56 C/mol)Q is the reaction quotient**The Nernst equation example problem shows how to use the Nernst equation to calculate cell potential of a non-standard cell.**At equilibrium, the reaction quotient Q i s the equilibrium constant, K. This makes the equation:Ecell E °cell - (RT/nF) x log10KFrom above, we know the following:Ecell 0 VE °cell 1.13 VR 8.3145 J/mol ·KT 25 degC 298.15 KF 96484.56 C/moln 6 (six electrons are transferred in the reaction)Solve for K:0 1.13 V - [(8.3145 J/mol ·K x 298.15 K)/(6 x 96484.56 C/mol)]log10K-1.13 V - (0.004 V)log10Klog10K 282.5K 10282.5K 10282.5 100.5 x 10282K 3.16 x 10282Answer:The equilibrium constant of the cells redox reaction is 3.16 x 10282.

Analysis of the Personality Traits of Steve Jobs

Steve Jobs is arguably one of the most successful CEOs of our times. In his time at Apple and Pixar he has redefined business across the Computing, Music and Mobile communications industries. In spite of being a college dropout he has gone on to become a technology and a business icon. His ability to achieve extraordinary success against tremendous odds makes him an extremely interesting personality to study. Following are his key personality traits. 1)Charismatic Charisma refers to the ability of a person to be able to mesmerise and hold the attention of others. Steve Jobs has charisma in ample abundance. His talks at the annual Macworld Expo have an attendance akin to that of a rock concert. People from all over the world flock in to listen to him for hours together as he delivers his famed talks on technology, innovation and Apple products. 2)Ingenious Ingenious is a rare personality trait that enables an individual to be clever, original and innovative. Prior to the launch of the iPod, the entire industry was looking at desktop publishing and the internet as new sources of revenue. Steve Jobs however was among the few who realised that there was latent demand in the MP3 player segment. He followed up on his insight by launching an iPod which had extremely innovative functions and a unique design. The product captured the attention of the world and along with his other innovation iTunes went on to change the way the world listens to music. Quite clearly he is an ingenious person. 3)Persistent Persistence is the ability of a person to stick to his convictions in spite of huge obstacles. With regard to this an early manager of his had commented that Steve never takes â€Å"no† for an answer For him â€Å"no† is only a comma and never a full stop. He will keep coming back till his objective is achieved. Years later his persistence was in ample display as he stubbornly stood his ground against internal opposition to his unconventional plan to turnaround Apple. 4)Unempathetic Empathy is the ability of an individual to understand Steve Jobs is known for pushing his employees to extreme limits. He is known for firing his employees often in an erratic fashion. This shows that he is unempathetic to people around him.

Case study-Intel Corp Study Example | Topics and Well Written Essays - 1500 words

-Intel Corp - Case Study Example The stakeholders of a company are the people who have a key stake in its operations or are affected by its activities. As such, it can be seen that the key stakeholders for Intel are many and these include the workers who work for the company. These people are responsible for performing the actual tasks in the organization. The management as well as other executive people in the company are also key stakeholders since they are responsible for controlling the activities taking place in the company. The clients of Intel are also major stakeholders since they contribute to its performance. The suppliers who provide the material used by Intel are also key stakeholders. The Company also distributes its products through different agents and these are also stakeholders for the organization. 2. Consumerisation of IT (CoIT) refers to the process where consumer technology is adopted for business purposes. For instance, it can be seen that mobile technology that is specifically meant for commun ication purposes among different individuals is now being used for conducting different types of business. Instead of just using communication technology for social communication purposes, most organizations are encouraging their employees to adopt this technology in their operations so that they improve their efficiency at work. If carefully harnessed, CoIT can significantly contribute to the performance of the company. If the employees are competent in the use of IT, they can improve productivity in the organization since they can process information at a faster rate. Basically, the use of IT in an organization is faster than information that is manually processed. CoIT also helps the employees to be innovative since they can devise new methods of performing their tasks at a faster rate. Data can be customised to suit the interests of the people involved such as the employees in the organization. The other benefit of CoIT to the organization is that it can easily link with the con sumers since they can also use different social media and applications to do business with the company. However, the risk that may be involved is that the hackers can take advantage of this to hack into other people’s accounts to steal their information. 3. Bring your own device (BYOD) should be encouraged at Intel. There are various aspects that ought to be taken into account when implementing this particular strategy in the organization. First and foremost, it must be noted that we are now living in an information society and most if not all aspects of business are now conducted through the use of information and communication technology (ICT) such as the internet. The internet is a network of computers that are linked and information can be instantly passed from one person to the other instantly regardless of distance. In the case of Intel, it can be seen that the company ought to carefully harness this strategy since it can help to improve efficiency with regards to the w ay the employees perform their tasks. Employees who perform tasks related to information processing and communication in the company should be encouraged to work from their homes using their own devices. If the employees are settled in one place, they are likely to be very productive in their work since they do not waste much of their time travelling to their workplaces. The strategy of BYOD can also help to create a sense of responsibility

Strategy As Simple Rules (Yahoo) Essay Example | Topics and Well Written Essays - 2000 words

Strategy As Simple Rules (Yahoo) - Essay Example Major local and multinational companies have been distinguished from each other, based on the strategies they use in their corporate operations and organization. In the case of Yahoo! as a case study, a lot can be said about the company’s identity in terms of its strategic management options and principles. Studies have actually showed that a lot of Yahoo!’s success since its establishment in 1994 can be attributed to the type of strategy that the company uses. In the option of Eisenhardt and Sull (2007), Yahoo! uses what is referred to as strategy as simple rules. The ideal behind this model of strategic management is to make good use of one’s opportunities on the market rather than pin one’s self to stringent book principles on strategies (Turner, 2002). In this essay therefore, four key areas or aspects of strategy as simple rules are outlined from the Yahoo! perspective. The first key point touches on zeroing in on key processes whiles the second key p oint is on simple rules for unpredictable markets. The third key point will elaborate the subject of what simple rules are not whiles the last key point delves into knowing when to change. The essay will be concluded with a summary and recommendation for Yahoo!’s implementation. ... What strategy as simple rules rather does for managers is that it helps them â€Å"pick a small number of strategically significant processes and craft a few simple rules to guide it† (Eisenhardt and Sull, 2007, p. 10). In effect, to zero in on key processes means to use processes as a means to get to the end, which has to do with the setting of rules. Even with this, the processes that will be picked must not be judged from its quantitative basis but on how quality and significant they are to achieving the corporate dream. Quite significantly, a number of companies including Yahoo! has zeroed in on key processes to ensure the creation of competitive advantage for themselves. At Yahoo! for instance, it is reported of how managers zeroed in on key processes by giving emphasis to branding and product innovation, where a four-point product innovation rule was set (Eisenhardt and Sull, 2007). Normally, the advantage with this approach have having fewer but highly significant proce sses to deal with is that it helps the company to keep focus of its strategic processes so as to ensure closer monitoring of these processes (Hammer and Champy, 2005). The realistic success that Yahoo! recorded when it introduced its four product innovation rules and gave much room for its developers to operate was that this product innovation that was not backed with many processes led to the creation of a new sport page, which had over 100,000 hits in only 48 hours (Eisenhardt and Sull, 2007). This is indeed a justification on the need to always find a means to zero in on key processes. Simple Rules for Unpredictable Markets Strategy as simple rules may have worked in several instances but its propagators insist that the need to constantly identify the best circumstances under which

Comparing and Contrasting High School Teachers and College Professors E

Most people see teachers and professors in the same light. They perform similar tasks. They teach. However, they are separated by a fine line of distinction. High school teachers help a student build a foundation of knowledge, and train the student to focus on learning. College professors help to shape and define a student’s foundation of knowledge, and challenge the student to cultivate the mind. High school teachers and college professors have similar goals and guidelines, but they take a differing approach to achieving the end result. The way the class is conducted, academic expectations, and view of student responsibility are a few of the contrasts between high school teachers and college professors. A high school class and a college class are conducted in different ways. In high school, teachers exercise control over the flow of information, while college professors encourage the student to seek out pertinent information. Throughout the year, a high school teacher will remind the student of upcoming due dates and assignment requirements. If a student misses a test or homework assignment, the teacher will provide missing notes or study guides so that the student is kept up to date with the rest of the class. For example; when I was in high school, I missed a week of school to go on vacation with my family. My mother spoke with my teacher before we left and he agreed to let me turn in my homework when I returned to class. Furthermore, my teacher allowed me to make up the single quiz that I missed during my absence. Neither the late homework, nor the missed quiz reflected in my grade. A college professor would have made me choose between a good grade and a vacation with my family. In contrast, the college professor... ...udent to monitor their own progress and find solutions to problems as they arise. A college professor will not listen to excuses, nor will the consequences of failure be withheld. For example; I failed a math final by a mere six points, but the rules dictate that a c minus is not passing. It was my responsibility to realize that I needed help with math before I took that final. I had to face the consequences and take the course again. A high school teacher provides a foundation of knowledge in preparation for the higher expectations of college. The college professor works to encourage independent learning, critical thinking, and self reliance. High school teachers and college professors may have differing points of view, but both affect the world as a whole. Henry Adams once said â€Å"A teacher affects eternity; he can never tell where his influence stops.’
