The standard e.m.f. of a cell, involving one electron change is found ...

The correct answer is option C
For a cell reaction in equilibrium at 298 K,
E^o_cell =0.0591/nlogK_c
(K_e = equilibrium constant)
Give, E^o_cell = 0.591V
Now, log K_c = (E^o_cell x n )/ 0.0591
=(0.0591 x n )/ 0.0591
log K_c = 10
K_c = antilog 10

K_c = 1 x 10¹⁰

Products of electrolysis depend on the nature of material being electrolysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gol d), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction. Thus, the products of electrolysis may be different for reactive and inert electrodes. Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells.In these questions, a statement of assertion followed by a statement of reason.
