For the cell reaction X(s) + 2Y^(+) ...

For the cell reaction
`X(s) + 2Y^(+) to X^2 + 2Y`
`k_c` has been found to be `10^12`. The `E_("Cell")^@` is :

A

0.708 V

B

1.36 V

C

0.354 V

D

1.006 V

Text Solution

Verified by Experts

The correct Answer is:
C
`E^(@)=(0.059)/(n) log K_(c)=(0.059)/(2) log 10^(12)`
`= 0.354 V`.
