Question 1

For the reaction 2 Al(s) + 3 Co2+(aq) → 2 Al3+(aq) + 3 Co(s), ΔG° is -799 kJ. What is E° for a standard cell based on this reaction?
◦ +2.76 V
◦ +8.28 V
◦ +4.14 V
◦ +1.38 V

Question 2

The nickel-cadmium battery cell has a standard potential of +1.20 V. The cell reaction is

2 NiO(OH)(s) + Cd(s) + 2 H2O(l) → 2 Ni(OH)2(s) + Cd(OH)2(s).


What is the standard free energy change for this reaction?
◦ -116 kJ
◦ -38.7 kJ
◦ -463 kJ
