Which is stronger reducing agent `Cr^(+2)` or `Fe^(+2)` ?

Explanation

`Cr^(+2)` is a stronger reducing agent then `Fe^(+2)` because `E^(6) (Cr^(+3)//Cr^(+2))` is - ve (- 0.41 V) whereas `E^(@)(Fe^(+3)//Fe^(+2))` is positive i.e., (0.77 V). Thus, `Cr^(+2)` is easily oxidised to `Fe^(+)Cr^(+3)` but `Fe^(+2)` cannot be easily oxidised to `Fe^(+3)` comparatively. Hence, `Cr^(+2)` is a stronger reducing agent than `Fe^(+2)`.
