Given the standard half-cell potentials (E\(^\circ\)) of the following as
$$\matrix{ {Zn \to Z{n^{2 + }} + 2{e^ - };} & {{E^o} = + 0.76V} \cr {Fe \to F{e^{2 + }} + 2{e^ - };} & {{E^o} = 0.41V} \cr }$$
Then the standard e.m.f. of the cell with the reaction \(F{e^{2 + }} + Zn \to Z{n^{2 + }} + Fe\) is
$$\matrix{ {Zn \to Z{n^{2 + }} + 2{e^ - };} & {{E^o} = + 0.76V} \cr {Fe \to F{e^{2 + }} + 2{e^ - };} & {{E^o} = 0.41V} \cr }$$
