Ionic Equilibrum

Using the Gibbs free energy change, $\Delta G^{\circ}=+63.3 \mathrm{~kJ}$. For the reaction,

\(\mathrm{Ag}_2 \mathrm{CO}_3 \longrightarrow 2 \mathrm{Ag}^{+}(a q)+\mathrm{CO}_3^{2-}(a q)\)

The $K_{\text {sp }}$ of $\mathrm{Ag}_2 \mathrm{CO}_3(s)$ in water at $25^{\circ} \mathrm{C}$ is
