For the reaction: \( \mathrm{Ag}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq}) \rightleftharpoons \mathrm{AgCl}(\mathrm{s}) \). Given
\begin{tabular}{lcc}
\( \mathbf{A g}^{+}+\mathrm{e}^{-} \rightarrow \mathbf{A g} ; E^{\circ}=\mathbf{0 . 8 0} \mathrm{V} \) & Species & \( \Delta G_{\mathrm{f}}^{\mathbf{0}}(\mathbf{k J} / \mathbf{m o l}) \) at \( \mathbf{2 5}^{\circ} \mathbf{C} \) \\
\cline { 2 - 3 } \( \mathrm{Zn}^{2+}+2 \mathrm{e}^{-} \rightarrow \mathbf{Z n} ; E^{\circ}=-\mathbf{0 . 7 6} \mathrm{V} \) & \( \mathrm{Ag}^{+}(\mathrm{aq}) \) & \( +77 \) \\
& \( \mathrm{Cl}^{-}(\mathrm{aq}) \) & \( -129 \) \\
& \( \mathrm{AgCl}(\mathrm{s}) \) & \( -109 \) \\
\cline { 2 - 3 } & \( \mathrm{K} \) is
\end{tabular}
The solubility product of \( \mathrm{AgCl} \) at \( 298 \mathrm{~K} \) is
(a) \( 2 \times 10^{-10} \)
(b) \( 10^{-10} \)
(c) \( e^{-10} \)
(d) \( 10^{-5} \)
