Following reactions occur at cathode during the electrolysis of aqueous copper (II) chloride solution:
`CU_((aq))^(2+)+ 2e^(-)rightarrow Cu_(s),` `E^(@) = + 0.34V`
`H_((aq))^(+) +e^(-) rightarrow (1)/(2)H_(2(s)),` `E^(@) = 0.00V`
On the basis of their standard reduction electrode potential `(E^(@))` values, which reaction is feasible at the cathode and why?
