Consider the following unbalanced oxidation-reduction reactions in aqueous solution:


(a) Balance each of the reactions.
(b) By using data in Appendix C, calculate ΔH° for each of the reactions.
(c) Based on the values you obtain for ΔH°, which of the reactions would you expect to be thermodynamically favored?
(d) Use the activity series to predict which of these reactions should occur. (Section 4.4) Are these results in accord with your conclusion in part (c) of this problem?
