1)
the balanced equation is
C2Cl6 + H2 ---> C2Cl4 + 2H+ + 2Cl-
we know that
dGo rxn = dGo products - dGo reactants
so
dGo rxn = dGo C2Cl4 + ( 2 x dGo H+ ) + ( 2 x dGo Cl-) - dGo H2 - dGo C2Cl6
dGo rxn = 28.7 + ( 2 x 0) + ( 2 x -131.3) - 0 + 51.5
dGo rxn = -182.4
so
dGo per moles of H2 consumed = -182.4 kJ
2)
the balanced equation is
S042- + 4H2 + 2H+ --> H2S + 4H20
dGo rxn = dGo H2S + ( 4 x dGo H20) - dGo S042- - ( 4 x dGo H2) + ( 2 x dGo H+)
dGo rxn = -27.8 + ( 4 x -237.1) + 744.8 - ( 4 x 0) + ( 2 x 0)
dGo rxn = -231.4 kJ / 4 mol H2
dGo rxn = -57.85 / mol H2 consumed
so
C2Cl6 yields more free energy per mole of H2
