Assertion(A): A catalyst speed up a reaction but does not participate in its mechanism. Reason(R): A catalyst provides an alternative path of lower activation energy to the reactants.

Products of electrolysis depend on the nature of material being electrlysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gold), 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 question, a statement of assertion followed by a statement of reason. choose the correct answer out of the following choices. Q. Assertion (A): At equilibrium condition E_(cell)=0 or Delta_(r)G=0 . Reason (R): E_(cell) is zero when both electrodes of the cell are of the same metal.
