Standard electrode potential are
`Fe^(2+)//Fe,E^(@)=-0.44 V `
`Fe^(3+)//Fe^(2+), E^(@)=0.77V`
`Fe^(2+),Fe^(3+) and Fe` block are kept together, then

Text Solution

Verified by Experts

The correct Answer is:
(Decreases, increases)
( Decrease, increases )
As `E^(c-)._(Fe^(3+)|Fe^(2+))gtE^(c-)._(Fe^(2+)|Fe)`
`:. Fe^(3+)` will get reduces to `Fe^(2+)` and `Fe` will get oxidized to `Fe^(2+)` . Hence `[Fe^(3+)]` decreases and `[Fe^(2+)]` increases.
