Calculation of Enthalpies of Reaction from Enthalpies of Formation AH reaction = Sum of enthalpies of products - Sum of enthalpies of reactants AH formation of any element in its pure state = 0 22. Find the enthalpy for the complete combustion of ethene: C₂H4(g) + 3 O2(g) → 2 CO₂(g) + 2 H₂O(g) 23. Calculate the enthalpy change for the reaction: Enthalpies of formation AH C₂H4(g) +52.30 kJ/mol AH CO₂(g) -393.5 kJ/mol AHf H₂O(g) -241.8 kJ/mol 2 Na(s) + 2 H₂O(l) → 2 NaOH(s) + H₂(g) AHf NaOH(s) = -102 kcal/mol AH, H₂O() = -68 kcal/mol Calculation of Enthalpies of Reaction from Enthalpies of Formation AH reaction = Sum of enthalpies of products - Sum of enthalpies of reactants AH formation of any element in its pure state = 0 22.
