Given the following reactions of nitrosyl chloride (NOCl), calculate the ∆H°rxn, in kilojoules per mole, for the third reaction. Enter your answer to the tenths place. Don’t forget the sign! 2NOCl(g) ⟶ 2NO(g) + Cl2 (g) ΔHrxn ° = +79.2 kJ mol ⁄

NOCl(g) + 1 2 O2 (g) ⟶ NO2Cl(g) ΔHrxn ° = -39.1 kJ mol ⁄

2NO(g) + Cl2 (g) + O2 (g) ⟶ 2NO2Cl(g)
