Problem Details

Using the enthalpy of reaction for the 2 reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone. 

ClO(g) + O3(g) → Cl(g) + 2O2(g)       ΔH°rxn =  -122.8 kJ

2O3(g) → 3O2(g)                               ΔH°rxn =  -285.3 kJ

O3(g) + Cl(g) → ClO(g) + O2(g)         ΔH°rxn = ?
