no. Of electrons transferred (n) = 30
E°cell = 0.15 V
Log K = E°cell * n / 0.0591
Log K = 0.15 * 30 / 0.0591
Log K = 76.142
K = 1.3 * 10^76
thus option (c) 1.3 * 10^76 is correct option.

An oxidation half-reaction is characterized by electrons appearing on the product side. The oxidation of aluminum for instance would be represented thusly: Al(s) → Al3+ + 3e- (1) An reduction half-reaction is characterized by electrons appearing on the reactant side. The reduction of ferrous iron for instance would be represented thusly: Fe2+ + 2e...
