cu2+ + 2e- = cu and h+ + 2e= 1/2h2 which is more feasible and why ?

Expert Answer:

The standard reduction potential for the reduction of copper is 0.34 V and that for the reduction of hydrogen is 0.0 V.
Higher reduction potential means that reduction reaction is more feasible.
Hence, Cu2+ + 2e- → Cu is more feasible.
