I have a revision question asking me to draw the energy cycle for the formation of Ethane C2H6 and use given values.
Would this just be a combustion energy cycle
So you have. 2C + 3H2 ------> C2H6
2CO2 + 3H2O
Therefore ΔHf + ΔH1 = ΔH2 + ΔH3
Therefore ΔHf = ΔH2 + ΔH3 - ΔH1
Or would it be different?
Regarding Hess's Law is ΔHf of Ethane the same as the Enthalpy of Combustion Watch

There seems to be information missing from your post, but your algebra at the end is correct. Not that I know what it applies to.
