Question
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 = 0. Heat of formation values can be used to calculate the enthalpy change of any reaction. Part A For which of the following reactions is AH equal to AH of the product(s)?You do not need to look up any values to answer this question !3! Check all that apply. Consider, for example, the reaction > View Available Hint(s) 2NO(g) + O2(g) = 2NO2(g) with heat of formation values given by the following table: O 2Na(s) + Ch (x)-2NACI(s) O H,O, (g)→02(g) + H,O(g) AH (kJ/mol) Substance NO(g) - Na(s) +C½(1)¬NACI(s) 90.2 O2(g) O 2H,(g) + O2(g)--2H,O(g) NO2 (g) 33.2 O H2(g) + 0,(g)→H,O(g) Then the standard heat of reaction for the overall reaction is o Na(s) +Cl, (g)¬NACI(s) AH= AH; (products)- AH (reactants) 2(33.2) 12(90.2) + 0) Submit Previous Answers Request Answer 114 kJ P Pearson 10:45 PM 3/2/2022 O DELL Insert CE delete AP prt sc F10 home end PU um backspace lock 7. 8.
