(20 points) Use the standard reduction potentials to answer the following questions Sn + 2e Sn(s) E = -0.141 v Zn° +2e Zn(s) E*=-0.762 v a. (2 points) Calculate the standard cell potential of the spontaneous reaction b. (4 points) Using the standard cell potential, determine the equilibrium constant c. (8 points) The cathode half-cell contains 0.50 M Sn" and the anode half-cell contains 0.010 M Zn?". Use the Nernst equation to determine the cell voltage. d. (6 points) Draw the spontaneous galvanic cell for the half-reactions. Assume that KCl is used as the salt bridge (Remember to label the electrodes and solutions in each half- cell, draw the directions of electron flow and anion flow)
