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^(10)`B. ` 1.0 xx 10^5`C. ` 1.0 xx 10^(1)`D. ` 1.0 xx 10^(30)` |
Answer» Correct Answer - A ` E_(Cell) = E_(Cell)^@ =0 rArr 0=0.591 - (0.0591)/n log K_C` ` log K_c = (0.591xx1)/( 0.0591) = 10 , K_c = `Anti `log 10 =1 xx 10^(10)`. |
