At 310 K, the galvanic reaction

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

has a standard cell potential of

E^\circ = 0.090\,\text{V}

and involves the transfer of one electron (

n=1

). The solution contains

[\mathrm{Fe^{3+}}]=0.20\,\text{M}

[\mathrm{Fe^{2+}}]=0.010\,\text{M}

[\mathrm{Sn^{4+}}]=1.0\times10^{-3}\,\text{M}

, and

[\mathrm{Sn^{2+}}]=0.50\,\text{M}

. Determine the cell potential,

E

, at 310 K. (Constants:

R=8.314\,\text{J\,mol}^{-1}\text{K}^{-1}

F=9.65\times10^{4}\,\text{C\,mol}^{-1}
