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?

Explanation

To determine which reaction is feasible at the cathode during the electrolysis of aqueous copper (II) chloride solution, we need to analyze the standard reduction potentials (E°) of the given half-reactions.
