Using two or more of the following,
N2(g) + 
O2(g) → N2O3(s) ; ΔH° = 83.7 kJ
N2(g) + O2(g) → 2NO(g) ; ΔH° = 180.4 kJ 
N2(g) + O2(g) → NO2(g) ; ΔH° = 33.2 kJ 
N2(g) + 
H2(g) → NH3(g) ; ΔH° = −45.9 kJ
Determine ΔH° for the following reaction.
NO(g) + NO2(g) → N2O3(g)
A) -39.7 kJ
B) 24.3 kJ
C) -207.1 kJ
D) 39.7 kJ
E) 207.1 kJ
