Problem

A galvanic cell based on the reaction

\text{A}^{+}+e^-\rightarrow \text{A}(s) \quad (E^{\circ}=0.10\,\text{V})

contains

\text{A}^{+}

ions at a concentration that gives

Q = 5.0

. At approximately what temperature will the cell potential drop to zero? (Use

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

and

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

.) a)

900\,\text{K}

720\,\text{K}

1.66\times10^{3}\,\text{K}

360\,\text{K}
