Multiple Choice
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 [ H f(NO) = 90.4 kJ/mol; H f(NO2) = 33.85 kJ/mol; H f(O3) = 142.2 kJ/mol]
A) -1690 kJ
B) -167 kJ
C) -97.6 kJ
D) -69.2 kJ
