\( \mathrm{P} \)
For the reaction: \( \mathrm{Ag}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq}) \rightleftharpoons \mathrm{AgCl}(\mathrm{s}) \). Given
\begin{tabular}{llc}
\cline { 2 - 3 } \( \mathbf{A g}^{+}+\mathrm{e}^{-} \rightarrow \mathbf{A g} ; E^{\circ}=\mathbf{0 . 8 0} \mathbf{V} \) & \multicolumn{1}{c}{ Species } & \( \Delta G_{\mathrm{f}}^{0}(\mathbf{k J} / \mathbf{m o l}) \) at \( \mathbf{2 5}{ }^{\circ} \mathbf{C} \) \\
\cline { 2 - 3 } \( \mathbf{Z n}^{2+}+2 \mathrm{e}^{-} \rightarrow \mathbf{Z n} ; E^{\circ}=-\mathbf{0 . 7 6} \mathrm{V} \) & \( \mathrm{Ag}^{+}(\mathrm{aq}) \) & +77 \\
& \( \mathrm{Cl}^{-}(\mathrm{aq}) \) & -129 \\
& \( \mathrm{AgCl}(\mathrm{s}) \) & -109 \\
\hline
\end{tabular}
