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. `1.0xx10^5`C. `1.0 xx 10^(10)`D. `1.0 xx 10^(1)`

Answer» Correct Answer - C
` E_("cell")^@ = (0059)/1 log K_C`
` 0.591= (0.059)/1 log K_C`
` :. K_c = 1 xx10^(01)`.
