The cell diagram for the reaction in which hydrogen gas reduces
Cu2+ (aq) is
Option A) Pt(s)I H2(g)I H+(aq)II Cu2+(aq)I Cu(s)
When Cu2+ get reduced to metallic Cu which was reduced by hydrogen gas. When hydrogen gas reduced other component it gets oxidized itself to H+ ion. In the cell redox diagram 1st half-reaction is for oxidation of hydrogen gas and 2nd half-reaction is for reduction of Cu2+ to metallic form.
