1. For the following reaction at 25 oC, under these conditions: [Fe2+] = 0.50 M, [Fe3+] = 0.10 M, [MnO4−] = 0.025 M, [Mn2+] = 0.015 M, and a pH of 7.00.
5Fe2+(aq) + MnO4−(aq) + 8H+(aq) ⇌ 5Fe3+(aq) + Mn2+(aq) + 4H2O(l)
Calculate
(a) the standard potential
(b) the equilibrium constant
(c) the potential
