The logarithm of the equilibrium constant of the cell reaction corresponding to the cell `X(s)|X^(2+)(aq)|| Y^(+)|Y(s)` with standard cell potential `E_("cell")^(@)=1.2V` is given by

A

12.5

B

21.5

C

40.5

D

47.2

Text Solution

Verified by Experts

The correct Answer is:
C
`E^(@)=(0.0591)/(n)"log"k(n=2)`
`therefore "log" k=(1.2xx2)/(0.591)=40.6`
