Ozone (O₃) in the Atmosphere Can Be Converted to Oxygen

question 65

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 8.50 L 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 (R = 0.0821 L atm/mol K) ? [ΔH°_f(NO) = 90.4 kJ/mol; ΔH°_f(NO₂) = 33.85 kJ/mol; ΔH°_f(O₃) = 142.2 kJ/mol]

• A) -69.1 kJ
• B) -19.7 kJ
• C) -1690 kJ
• D) -97.6 kJ
• E) -167 kJ
