E^(@) for the electrochemical cell Zn(...

`E^(@)` for the electrochemical cell
`Zn(s)|Zn^(2+) 1 M (Aq.)||Cu^(2+) 1 M (aq.)|Cu(s)`
is 1.10 V at `25^(@)C`. The equilibrium constant for the cell reaction,
`Zn(s) +Cu^(2+) (aq.) hArr Zn^(2+) (aq.)+Cu(s)`
Will be :

A

`10^(-37)`

B

`10^(37)`

C

`10^(-39)`

D

`10^(39)`

Text Solution

Verified by Experts

The correct Answer is:
B

K = antilog `[(nE^(@))/0.0591]`
= antilog `[(2xx1.10)/0.0591]=1.67xx10^(37)`
