The standard emf of a cell having one el...

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 xx10^(1)`

B

`1.0 xx10^(5)`

C

`1.0 xx10^(10)`

D

`1.0 xx10^(30)`

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(cell)^(@)=(0.0591)/(n) log k_(eq)`
`0.591=(0.591)/(1) log k_(eq)`
`therefore log k_(eq)=10`
`therefore k_(eq)=1xx10^(10)`
