    Q:

    		 The potential of a galvanic cell is measured at 0.36 V. If one of the half cell reactions is Cd2+ + 2e- → Cd (-0.40 V) which occurs as the reduction reaction. Which of the following could be the other half cell reaction?
    		 

    A

    		 ClO3- + H2O + 2e- → ClO2- + 2OH- (0.36 V)

    B

    		 Fe3+ + e- → Fe2+ (0.76 V)

    C

    		 Fe2+ + 2e- → Fe (-0.36 V)

    D

    		 Zn2+ + 2e- → Zn (-0.76 V)
