Problem

Consider the balanced redox reaction below, carried out under standard conditions:

\mathrm{Sn^{2+}}(aq) + 2\,\mathrm{Fe^{3+}}(aq) \rightarrow \mathrm{Sn^{4+}}(aq) + 2\,\mathrm{Fe^{2+}}(aq)

The standard cell potential is

E^{\circ}_{\text{cell}} = +0.15\,\text{V}

. Using

F = 96{,}485\,\text{C mol}^{-1}

, calculate the standard Gibbs free energy change

\Delta G^{\circ}

(in kJ per mole of reaction).
