Enthalpy Change of Propane Combustion

In a closed system, the combustion of propane (C₃H₈) releases heat energy. The balanced chemical equation for the complete combustion of propane is:

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat.

Given the molar enthalpy of formation (ΔH_f) for propane is -104 kJ/mol, carbon dioxide is -394 kJ/mol, and water is -286 kJ/mol, calculate the enthalpy change (ΔH_rxn) for the combustion reaction of 1 mole of propane.
