The standard emf of a cell having one electron change is found to be `0.591 V` at `25^@ C`, The equilibrium constant of the reaction is :A. `1.0 xx 10^(30)`B. `1.0 xx 10^(5)`C. `1.0 xx 10^(10)`D. `1.0 xx 10^(1)`

Answer» Correct Answer - C
`E_(cell)^(@) = (0.059)/(1)log K_(c)`
`0.591 = (0.059)/(1)log K_(c)`
`:. K_(c) = 1 xx 10^(10)`
