Standard electrode potentials are
Fe2+/Fe [Eo = 0.44] and
Fe3+/Fe2+[ Eo = 0.77];
If Fe2+, Fe3+ and Fe blocks are kept together, then
Fe2+/Fe [Eo = 0.44] and
Fe3+/Fe2+[ Eo = 0.77];
If Fe2+, Fe3+ and Fe blocks are kept together, then
- AFe3+ increases
- BFe3+ decreases
- CFe2+/Fe3+ remains unchanged
- DFe2+ decreases.

Correct answer: B
The metals having higher negative values of their electrode potential can displace metals having lower values from their salt solutions.
