Given that: \[E{{{}^\circ }_{A{{g}^{+}}/Ag}}~=0.80V\] and \[[A{{g}^{+}}]={{10}^{-3}}M;\] \[E{{{}^\circ }_{Hg_{2}^{2+}/Hg}}=0.785V\] and \[[Hg_{2}^{2+}]={{10}^{-1}}M\] which is true for the cell reaction \[2Hg(l)+2A{{g}^{+}}(aq)\to 2Ag(s)+Hg_{2}^{2+}(aq)?\]

• A. The forward reaction is spontaneous
• B. The backward reaction is spontaneous
• C. \[{{E}_{cell}}=0.163\,\nu \]
• D. \[{{E}_{cell}}=1.585\,\nu \]
