Solution: Calculate ΔHrxn for the following reaction 2 NOCl (g) → N2 (g) + 02 (g) + Cl2 (g) Given the following set of reactions; 1/2 N2 (g) + 1/2 02 (g) → NO (g)          ΔH= 90.3KJ NO (g) + 1/2 Cl2 (g) → N

Problem

Calculate ΔHrxn for the following reaction

2 NOCl (g) → N(g) + 0(g) + Cl(g)

Given the following set of reactions;

1/2 N(g) + 1/2 0(g) → NO (g)          ΔH= 90.3KJ
NO (g) + 1/2 Cl(g) → NOCl (g)          ΔH = - 38.6 KJ
