Formation Reactions Correct The standard heat of formation, Î}, is defined as For both of these of AH ng like the enthalpy change for the formation of one mole of substance from its constituent states. Thus, f the reaction would not be equal to Î HÇ for the product. t for the product were not 1, or if the reactants were not hen states have Î = 0, Heat of formation values can be used to calculate the enthalpy change of any reaction. Part B 2N0(g) + O2 (g) 2NO2 (g) with heat of formation values given by the following table: CsH4 (g) + 502 (g)â3CO2 (g) + 4H20(g) Substance (kJ/mol) Substance (J/mol) C3Hs (g) 104.7 CO2(8)-3935 H2O(g)241.8 Calculate the enthalpy for the combustion of 1 mole of propane. Express your answer to four significant figures and include the appropriate units NO(g) 902 O,(8) NO2(8) 33.2 Then the s A, (products)-Ar(reactants) 2(33.2) -114 kJ Hrx.- -12(90.2) + ì´ Hints = Hron . | Value | Units
