    \[Ag|AgCl||C{{l}^{-}}({{C}_{2}})||C{{l}^{-}}({{C}_{1}})|AgCl|Ag\]for this cell\[\Delta G\]is negative if

    A)  \[{{C}_{1}}={{C}_{2}}\]                 

    B)  \[{{C}_{1}}>{{C}_{2}}\]

    C)  \[{{C}_{2}}>{{C}_{1}}\]                 

    D)  Both (a) and (b)

    Correct Answer: C

    Solution :

                    Given cell is electrolyte concentration cell \[{{E}_{cell}}=\frac{RT}{F}\]in \[\frac{[A{{g}^{+}}]RHS}{[A{{g}^{+}}]LHS}\] Where,     \[[A{{g}^{+}}]=\frac{{{K}_{sp}}}{[C{{l}^{-}}]}\] For spontaneous chemical charge concentration. of \[A{{g}^{+}}\]of cathodic compartment must be greater than anodic compartment.
