Answer:

Molar Heat of Combustion (molar enthalpy of combustion) of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at constant pressure. By definition, the heat of combustion (enthalpy of combustion, ΔHc) is minus the enthalpy change for the combustion reaction, ie, -ΔH.
