Calculate the Enthalpy Change for the Reaction NO(g) + O(g)

question 13

Multiple Choice

Calculate the enthalpy change for the reaction NO(g) + O(g) → NO₂(g)
From the following data:
NO(g) + O₃(g) → NO₂(g) + O₂(g) ΔH = −198.9 kJ
O₃(g) → 1.5O₂(g) ΔH = −142.3 kJ
O₂(g) → 2O(g) ΔH = 495.0 kJ

• A)−551.6 kJ
• B)−304.1 kJ
• C)190.9 kJ
• D)153.8 kJ
• E)438.4 kJ
