Ozone (O3) in the atmosphere can be converted to oxygen gas by reaction with nitric oxide (NO).  Nitrogen dioxide is also produced in the reaction.  What is the enthalpy change when 8.50L of ozone at a pressure of 1.00 atm and 25°C reacts with 12.00 L of nitric oxide at the same initial pressure and temperature? [ΔH°f(NO) = 90.4 kJ/mol; ΔH°f(NO2) = 33.85 kJ/mol; ΔH°f(O3) = 142.2 kJ/mol]

▸ –1690 kJ

▸ –167 kJ

▸ –97.6 kJ

▸ –69.2 kJ

▸ –19.7 kJ
