Problem

Three half-reactions and their standard reduction potentials at 298 K are listed below:

Cl_{2}(g) + 2\,e^- \rightarrow 2\,Cl^-

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

Pb^{2+} + 2\,e^- \rightarrow Pb

E^\circ = -0.13\,\text{V}

Sn^{2+} + 2\,e^- \rightarrow Sn

E^\circ = -0.14\,\text{V}

Construct a balanced overall redox equation for the galvanic cell that yields the greater

E^\circ_{\text{cell}}

and calculate that standard cell potential.
