Using Hess's law, what is ΔH°rxn for the following reaction?

NO(g) + O(g) → NO2(g)

 NO(g) + O3(g) → NO2(g) + O2(g)

ΔH°rxn = 198.8 kJ/mol

 O3(g) → 3/2 O2(g)

ΔH°rxn= 142.2 kJ/mol

 O2(g) → 2O(g)

ΔH°rxn= +498.8 kJ/mol



▸ –839.8 kJ/mol

▸ –306.0 kJ/mol

▸ 157.9 kJ/mol

▸ 394.9 kJ/mol

▸ 442.3 kJ/mol
