Using the Gibbs change, $∆{\mathrm{G}}^{\mathrm{o}}=+63.3\mathrm{ }\mathrm{k}\mathrm{J},$ for the following reaction, $\mathrm{A}{\mathrm{g}}_2\mathrm{C}{\mathrm{O}}_3\left(\mathrm{g}\right)\mathrm{ }\rightleftharpoons 2\mathrm{A}{\mathrm{g}}^{+}\left(\mathrm{a}\mathrm{q}\right)+\mathrm{C}{\mathrm{O}}_3^{2-}\left(\mathrm{a}\mathrm{q}\right)$ the ${\mathrm{K}}_{\mathrm{s}\mathrm{p}}$ of $\mathrm{A}{\mathrm{g}}_2\mathrm{C}{\mathrm{O}}_3\left(\mathrm{s}\right)$ in water at ${25}^{\mathrm{o}}\mathrm{C}$ is $\left(\mathrm{R}=8.314\mathrm{ }\mathrm{J}{\mathrm{K}}^{-1}\mathrm{m}\mathrm{o}{\mathrm{l}}^{-1}\right)$

• A

  $3.2\times {10}^{-26}$
• Correct answer
  B

  $8.0\times {10}^{-12}$
• C

  $2.9\times {10}^{-3}$
• D

  $7.9\times {10}^{-2}$

Hence, the correct answer is option: 'B'.
