The standard Gibbs free energy change for the reaction Cu2+(aq)+2 Cl−(aq)→Cu(s)+Cl2(g)\mathrm{Cu}^{2+}(\mathrm{aq}) + 2\,\mathrm{Cl}^{-}(\mathrm{aq}) \rightarrow \mathrm{Cu}(s) + \mathrm{Cl}_2(g) is ΔG∘=+1.30×102 kJ\Delta G^\circ = +1.30 \times 10^2\,\text{kJ} per mole of reaction as written. If 2 mol e−2\,\text{mol}\, e^{-} are transferred, determine the minimum cell potential (in V) that must be applied at 298 K298\,\text{K} to make this reaction occur. (Faraday constant F=9.6485×104 C mol−1 e−F = 9.6485 \times 10^4\,\text{C mol}^{-1}\, e^{-}.)
