(1) N2O4(g) →2 NO2(g) ΔH= +57.9 kJ
(2) 2 NO(g) + O2(g) → 2 NO2(g) ΔH -113.1 kJ
We shall modify the given reactions to arrive at the overall reaction. Any modification to the reaction is reflected in the value of ΔH for the reaction.

Calculate ΔH for 2 NO(g) + O2(g) → N2O4(g) using the following information:
N2O4(g) →2 NO2(g) ; ΔH= +57.9 kJ
2 NO(g) + O2(g) → 2 NO2(g) ; ΔH -113.1 kJ
