At 310 K, a cell operates according to the reaction

Ag^{+}(\text{aq}) + Fe^{2+}(\text{aq}) \rightleftharpoons Ag(\text{s}) + Fe^{3+}(\text{aq})

with

E^{\circ}_{\text{cell}}=0.80\,\text{V}

. The solution contains

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

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

, and

[\text{Ag}^{+}]=0.050\,\text{M}

. What is the cell potential at 310 K? (Assume ideal behavior for all species.) (a)

0.96\,\text{V}

(b)

0.64\,\text{V}

(c)

0.48\,\text{V}

(d)

0.72\,\text{V}
