The destruction of the ozone layer by chlorofluorocarbons (CFCs) can be described by the following reactions:
ClO(g) + O3(g) ----> Cl(g) + 2 O2(g) (ΔHrxn = -29.90 kJ)
2 O3(g) ----> 3 O2(g) (ΔHrxn = 24.18 kJ)
Determine the value of heat reaction for the following:
Cl(g) + O3(g) ----> ClO(g) + O2(g) (ΔHrxn = ?)
