Question
For a cell reaction involving two electron change, the standard EMF of the cell is 0.295 V at 2oC. The equilibrium constant of the reaction at 25oC will be
Options
A.25.5 × 10-2
B.10
C.1 × 1010
D.2.95 × 10-10
Solution
Eocell = 
logKc = 
logKc
∴ 0.295V =
logKc
or log Kc =
= 10
or Kc = 1 × 1010
logKc = logKc∴ 0.295V =
logKcor log Kc =
= 10or Kc = 1 × 1010
