Question

For each of the following pairs of half-cells:

a. Write a balanced chemical equation for each half-reaction and the overall reaction.

b. Determine E°cell for the reaction.

c. Is the cell spontaneous as written?

d. Calculate ΔG°rxn for the cell reaction.

Anode: Al(s)  Al+3(aq) Ered = -0.1238V             

Cathode: I2(aq)  I-1(aq) Ered = +0.5273V

Anode: NO3-1(aq)  HNO2(aq) Ered = +0.9513V

Cathode: Cr+3(aq)  Cr(s) Ered = +0.7237V

Anode: ClO4-1(aq)  Cl2(aq) Ered = +1.2407V

Cathode: Cr2O7-2(aq)  Cr+3(aq) Ered = +1.2315V
