E^@ values for the half cell reactions a...

`E^@` values for the half cell reactions are given below :
`Cu^(2+) + e^(-) to Cu^(+) , E^@`=0.15 V
`Cu^(2+) + 2e^(-) to Cu, E^@`=0.34 V
What will be the `E^@` of the half-cell : `Cu^(+) + e^(-) to Cu` ?

A

Co

B

`Co^(2+)`

C

Cr

D

`Cr^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
b
Reduction potential of `Co^(2+)` is more, so it is stronger oxidant.
