The electrode potentials for
`Cu^(2+)+e^(-)toCu^(+)` and
`Cu^(+)e^(-)toCu_(s)`
are `+0.15`V and `+0.50V` respectively the value of `E_((Cu^(2+))/(Cu))^(@)` will be?

A

0.150 V

B

0.500V

C

0.325V

D

0.650V

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaG_(3)=DeltaG_(1)+DeltaG_(2)`
`implie-2FE^(@)+-1Fxx0.15+(-1Fxx0.50)`
`implies-2FE^(@)-0.15F-0.50F`
`implies2FE^(@)=-F(0.15+0.50)`
`thereforeE^(@)=(0.65)/(2)=0.325` volt.
