    Which will increase the voltage of the cell \[S{{n}_{(s)}}+2A{{g}^{+}}_{(aq)}\to S{{n}^{2+}}_{(aq)}+2A{{g}_{(s)}}\]                [DPMT 2001]

    A)                 Increase in the concentration of \[A{{g}^{+}}\]ions

    B)                 Increase in the concentration of \[S{{n}^{2+}}\]ions

    C)                 Increase in size of the silver rod

    D)                 None of these

    Correct Answer: A

    Solution :

                    \[{{E}_{\text{cell}}}=E_{\text{cell}}^{o}+\frac{0.059}{2}\log \frac{(A{{g}^{+}})}{(S{{n}^{2+}})}\].
