Given Fe^(3+)(aq)+e ^(-)toFe ^(2+)(aq)...

Given
`Fe^(3+)(aq)+e ^(-)toFe ^(2+)(aq), E ^(@) =+0.77V`
`Al ^(3+) (aq)+ 3e ^(-)to Al(s),E^(@)=-1.66V`
`Br_(2) (aq)+ 2e^(-) to 2Br,E^(@)=+ 1.09V`
Considering the electrode potentials, which of the following represents the correct order of reducing power?

A

`Fe ^(2+)lt Al lt Br^(-)`

B

`Br ^(-) lt Fe ^(2+) lt Al`

C

`Al lt Br lt Fe ^(2+)`

D

`Al lt Fe ^(2+) lt Br `

Text Solution

Verified by Experts

The correct Answer is:
D

Reducing character decrease down the sereies. Hence the correct order is
`Al lt Fe^(2+) lt Br ^(-)`
