Based on the data given below, the correcy order of reducing power is: Fe_((aq.))^(3+) + e rarr Fe_((aq.))^(2+), E^(@) = +0.77 V Al_((aq.))^(3+) + 3e rarr Al_((s)), E^(@) = -1.66 V Br_(2(aq.)) + 2e rarr 2Br_((aq.))^(-), E^(@) = +1.08 V

Answer»

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

Solution :Lower the REDUCTION potential, more is the REDUCING power .
`Br^-` lt `Fe^(2+)` lt Al
