###### Question:

ormation Reactions Review Constants Part B The standard heat of formation, AH is defined as the enthalpy change for the formation of one mole of substance from its constituent elements in their standard states. Thus, elements in their standard states have AH O . Heat of formation values can be used to calculate the enthalpy change of any reaction. The combustion of propano, C, Hs. cocurs via the reaction CH, (B) +502 (6)+3CO2 (s) + 4H2O(g) with heat of formation values given by the following table: Substance (kJ/mol Consider, for example, the reaction 2NO(g) + O2(e) = 2NO, (8) with heat of formation values given by the following table: Γ ΔΗΣ Γ ΔΗ 047 Substance (kJ/mol) CH CO, (8) H,OR) - 241.8 NO() 0.(g) NO,(g) 90.2 0 332 Calculate the enthalpy for the combustion of 1 mole of propane. Express your answer to four significant figures and include the appropriate units. View Available Hints) Then the standard heat of reaction for the overall reaction is AH - AH (products) - AH (reactants) = 2(33.2) - 2(90.2) +01 114 kJ at - O! Value RO? Units Submit
