# The standard e.m.f. of a galvanic cell involving cell reaction with n = 2 is found to be 0.295 V a 25ºC. The equilibrium constant of the reaction would be :- <br> (Given $F = 96500 \;C \;mol^{–1}$; <br> $R = 8.314 JK^{–1} mol^{–1}$)
( A ) $4.0\times 10^{12}$
( B ) $2.0\times 10^{11}$
( C ) $1.0\times 10^{2}$
( D ) $1.0\times 10^{10}$
