Solution: Given the dataN2 (g) + O2 (g) → 2 NO (g)            ΔH = +180.7 kJ2 NO (g) + O2 (g) → 2 NO2 (g)      ΔH = -113.1 kJ2 N2O (g) → 2 N2 (g) + O2 (g)       ΔH = -163.2 kJuse Hess’s law to calculate ΔH for

Given the data
N₂ (g) + O₂ (g) → 2 NO (g)            ΔH = +180.7 kJ
2 NO (g) + O₂ (g) → 2 NO₂ (g)      ΔH = -113.1 kJ
2 N₂O (g) → 2 N₂ (g) + O₂ (g)       ΔH = -163.2 kJ

use Hess’s law to calculate ΔH for the reaction
N₂O (g) + NO₂ (g) → 3 NO (g)
