The standard e.m.f. of a cell, involving one electron change is found to be \( 0.591 \mathrm{~V} \) at \( 25^{\circ} \mathrm{C} \). The equilibrium constant of the reaction is \( \left(\mathrm{F}=96,500 \mathrm{C} \mathrm{mol}^{-1} ; \mathrm{R}=8.31 .4 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}\right) \)
\( \mathrm{P} \)
(A) \( 1.0 \times 10^{30} \)
(B) \( 1.0 \times 10^{5} \)
(C) \( 1.0 \times 10^{10} \)
(D) \( 1.0 \times 10^{1} \)
