Regarding Hess's Law is ΔHf of Ethane the same as the Enthalpy of Combustion
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
\ /
\ /
v v
2CO2 + 3H2O
Therefore ΔHf + ΔH1 = ΔH2 + ΔH3
Therefore ΔHf = ΔH2 + ΔH3 - ΔH1
Or would it be different?
