If E(Fe^(3+)//Fe)^(@) and E(Fe^(2+)//Fe)...

If `E_(Fe^(3+)//Fe)^(@)` and `E_(Fe^(2+)//Fe)^(@)` are `-0.36 V` and `0.439 V` respectively, then value of `E_(Fe^(3+)//Fe^(2+))^(@)` is

Text Solution

Verified by Experts

`E^(@)` for the reaction is `0.771 - 0.800 = -0.029 `V .
Therefore , the reaction is not spontaneous .
