Enthalpy |

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 the reactionN2O (g) + NO2 (g) → 3 NO (g)

Given the data

N_{2} (g) + O_{2} (g) → 2 NO (g) ΔH = +180.7 kJ

2 NO (g) + O_{2} (g) → 2 NO_{2} (g) ΔH = -113.1 kJ

2 N_{2}O (g) → 2 N_{2} (g) + O_{2} (g) ΔH = -163.2 kJ

use Hess’s law to calculate ΔH for the reaction

N_{2}O (g) + NO_{2} (g) → 3 NO (g)
