The reduction potential of hydrogen half-cell will be negative if

Reduction hydrogen half-cell is H+zMPt(H2);Pressure pH2Half-cell reaction is 2H+aq+2e-→H2(g)Reaction quotient =Q=pH2/H+2and n=2Ecello=Eredo-0.0591nlog Q=0-0.05912log QEredo=0.00 Vfor standard hydrogen electrode If Q>1,then Eredo=-ve Thus, correct answer is (c ).
