TheE(M^(3+)//M^(2+))^(@)values forCr,Mn,...

The`E_(M^(3+)//M^(2+))^(@)`values for`Cr,Mn,Fe andCo`are `0.41,+1.57,+0.77`and`+1.97`V respectively .For which one of these metal the change in oxidation state from`+2`to`+3`is easiest:

A

`Co`

B

`Mn`

C

`Fe`

D

`Cr`

Text Solution

Verified by Experts

The correct Answer is:
D
More is`E_(RP)^(o)`,more is the tendency to get reduced or lesser is tendecy to get oxidised`E_(RPCr^(3+)//Cr^(2+))^(o)` is maximum among all.
