Problem

Consider a galvanic cell constructed from the following two standard half-reactions.

\mathrm{Cl_2(g) + 2\,e^- \rightarrow 2\,Cl^-(aq)}

E^\circ = +1.36\,\mathrm{V}

\mathrm{I_2(s) + 2\,e^- \rightarrow 2\,I^-(aq)}

E^\circ = +0.54\,\mathrm{V}

Calculate

\Delta G^\circ

(in

\mathrm{kJ}

) for the spontaneous cell reaction at

298\,\mathrm{K}

. Use

F = 9.65 \times 10^4\,\mathrm{C\,mol^{-1}}
