Given reaction is Mn(s) +
Cd+2(aq)
Mn+2(aq) + Cd(s)
Where the reduction half-reaction:
Cd+2(aq) + 2e- Cd(s)
Eored = -0.403 V
the oxidation half-eaction is:
Mn(s)
Mn+2(aq) + 2e-
Eored = -1.185 V
Eo of cell = Eored of reduction half-raection - Eored of oxidation half-reaction = -0.403 - (-1.185) = +0.782 V.
We should answer only one question.
