The standard `E_(red)^(@)`Values if A, B and C are `+ 0.68V`, -`0.76V`, `-0.50V` respectively.
The order of their reducing power is :

A

`AgtBgtC`

B

`AgtCgtB`

C

`CgtBgtA`

D

`BgtCgtA`

Text Solution

Verified by Experts

The correct Answer is:
D
Lower is reduction potential, greater is the tendency to get oxidised and greater is reducing power.
