Question

Consider the following unbalanced oxidation-reduction
reactions
in aqueous solution:
Ag+(aq) + Li(s)----> Ag(s) + Li+(aq)
Fe(s) + Na+(aq)----> Fe2+ (aq) + Na(s)
K(s) + H2O(l)---->KOH(aq) + H2(g)
(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. Are these results in accord
with your conclusion in part (c) of this problem?
