Formation ReactionsCorThe standard heat of formation, AH, is defined as theenthalpy change for the formation of one mole ofsubstance from its constituent elements in theirstandard states. Thus, elements in their standard stateshave AH =0. Heat of formation values can be usedto calculate the enthalpy change of any reaction.with heat of fomation values given by the following table:Substance(kJ /mol)CHs (g)104.7CO2(g)393 5Consider, for example, the reactionH2O(g)-241.82NO(g) + O2(g)=2NO2(g)with heat of formation values given by the followingCalculate the enthalpy for the combustion of 1 mole of propane.table:Express your answer to four significant figures and include the appropriate uAH(kJ/mol)SubstanceView Available Hint(s)NO(g)90.2O2 (g)NO2(g)33.2AH =ValueUnitsThen the standard heat of reaction for the overallreaction isSubmitAHn= AH (products)- AH (reactants)[2(90.2) + 0]2(33.2)-114 kJProvide FeedbackP Pearson田
