Question:

Using the standard reduction potentials listed in Appendix E, calculate the equilibrium constant for each of the following reactions at 298 K:
(a) Fe(s) + Ni2+(aq) → Fe2+ (aq) + Ni(s)
(b) Co(s) + 2 H+ (aq) → Co2+(aq) + H2(g)
(c) 10 Br- (aq) + 2 MnO4- (aq) + 16 H+(aq) → 2 Mn2+(aq) + 8 H2O(l) + 5 Br2(l)
