$Ag(s)\,\,|\,\,A{g_2}{C_2}{O_4}(s)\,\,|\,\,{C_2}O_4^{2 - }(0.02\,M)\,\,||\,\,A{g^ + }(0.5\,M)\,\,|\,\,Ag(s)$
$EMF$ of cell is $0.264\ V$ at $25\,^oC$ . $K_{sp}$ of $Ag_2C_2O_4(s)$ is
$\left[ {Given = \frac{{2.303 \times 8.314 \times 298}}{{96500}} = \frac{{2.303RT}}{F} = 0.06,\,\log 2 = 0.3} \right]$
