Answer :

(iii) Assertion is true but the reason is false.

Ecell should have a positive value for the cell to function. As,we know,

ΔrGcell = -nFEcell

Where, ΔrGcell = Gibbs free energy of the reaction.

For the proper functioning of the cell, the reaction must be spontaneous, i.e., ΔrGcell should have a negative value and this is true only when Ecell have a positive value.

We know, Ecell = Ecathode – Eanode

For reaction to be spontaneous, Ecell should have a positive value. This is true only when Ecathode > Eanode.
