Calculate the value of ΔHo for the reaction
2 CH4 (g) -> C2H6 (g) + H2 (g)
given the following thermochemical equations:

C2H2 (g) + H2 (g) -> C2H4 (g) ΔHo = 175.1 kJ

C2H6 (g) -> C2H4 (g) + H2 (g) ΔHo = + 136.4 kJ

C2H2 (g) + 3 H2 (g) -> 2 CH4 (g) ΔHo = 376.8 kJ


a) + 65.3 kJ
b) + 338.1 kJ
c) 415.5 kJ
d) + 688.3 kJ
