Graphing Calculator Calculate the Equilibrium Constant, using the Standard Cell Voltage The graphing calculator can run a program that calculates the equilibrium constant for an electrochemical cell using an equation called the Nernst equation, given the standard potential and the number of electrons transferred. Given that the standard potential is 2.041 V and that two electrons are transferred, you will calculate the equilibrium constant.The program will be used to make the calculations. Go to Appendix C. If you are using a TI-83 Plus, you can download the program NERNST and data and run the application as directed. If you are using another calculator, your teacher will provide you with keystrokes and data sets to use. After you have run the program, answer the following questions. a. What is the equilibrium constant when the standard potential is 0.099? b. What is the equilibrium constant when the standard potential is 1.125? c. What is the equilibrium constant when the standard potential is 2.500?
