I guess I should specify. The way I calculated the enthalpy of combustion was by subtracting the enthalpies of formation for the reactants from those of the products--a generic way to get the enthalpy change for any reaction. However, since water (gas) has a higher Hf, the overall H of the...

Expansion Work -- Still confused. This is more of a general question regarding thermodynamics. If you have a combustion reaction, and it produces either liquid water or water vapor--which case results in higher expansion work? My enthalpy calculations show higher PV work for the reaction with...
