Standard electrode potentials are : Fe...

Standard electrode potentials are :
`Fe^(2+) "|" Fe (E^(@) = - 0.44 V), Fe^(3+) "|" Fe^(2+) (E^(@) = 0.77 V) Fe^(2+), Fe^(3+)` and Fe blocks 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.
