    Q:

    		 Using the standard half-cell potentials for the reactions below, identify the reaction which will be spontaneous.

    Ba2+ + 2e- ↔ Ba -2.90 V
    Mn2+ + 2e- ↔ Mn -1.04 V
    K+ + e- ↔ K -2.92 V
    2H+ + 2e- ↔ H2 0.00 V
    I3- + 2e- ↔ 3I- 0.53 V
    		 

    A

    		 Ba2+ + Mn ↔ Mn2+ + Ba

    B

    		 K + Ba2+ ↔ K+ + Ba

    C

    		 3I- + 2H+ ↔ I3- + H2

    D

    		 K+ + I3- ↔ 3I- + K
