Given , Cu^(2+) + e^(-) to Cu^(+) E^(@) ...

Given , `Cu^(2+) + e^(-) to Cu^(+) E^(@) = 0.15 " volt " , Cu^(+) + e^- to Cu E^(@) = 0.5` volt
Calculate potential for `Cu^(2+) + 2e^(-) to Cu`

A

`0.65 V `

B

`0.325 V `

C

`0.45 V `

D

`1.2 V `

Text Solution

Verified by Experts

The correct Answer is:
B
`(3)= (1) +(2) ,DeltaG_(3)^(0) = DeltaG_(1)^(0) + DeltaG_2^(0) , 2E_(3)^(0) = (1E_(1)^(0) + 1E_(2)^(0))=(0.15 + 0.5)/(2) = (0.652)/(2),E_3^(0) = 0.325 V `
