Given `E^(c-)._(Fe^(2+)|Fe)` and `E^(c-)._(Fe^(3+)|Fe^(2+))` are `-0.44` and `0.77V` respectively. If `Fe^(2+),Fe^(3+)` and `Fe` blocks are kept together, then `[Fe^(3+)]` `……………………` and `[Fe^(2+)]…………………….` .

Answer» Correct Answer - (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.
