Q 2640580413.     (a) Following reactions occur at cathode during the electrolysis of aqueous sodium chloride solution:

`Na^+(aq) + e^(-) ⟶ Na (s) ;E^0 = - 2.71 V`
`H^+(aq) + e^(-) ⟶1/2 H_2 (g) ; E^0 = 0.00 V`
On the basis of their standard reduction electrode potential `(E^0)` values, which reaction is feasible at the cathode and why?

(b) Why does the cell potential of mercury cell remain constant throughout its life?
