Three common hydrocarbons that contain four carbons are listed here, along with their standard enthalpies of formation:
C4H6(g) 111.9 kJ/mol
C4H8(g) 1.2 kJ/mol
C4H10(g) -124. kJ/mol
For each substance, calculate the molar enthalpy of combustion to CO2(g) and H20(l) and fuel value in kJ/g for each compound.
