Oxygen atoms can combine with ozone to form oxygen:
O3(g) + O(g) → 2 O2(g)
ΔrH° = −392 kJ/mol-rxn
Using ΔrH° and the bond dissociation enthalpy data in Table 8.8, estimate the bond dissociation enthalpy for the oxygen-oxygen bond in ozone, O3. How does your estimate compare with the energies of an O—O single bond and an O=O double bond? Does the oxygen-oxygen bond dissociation enthalpy in ozone correlate with its bond order?
O2(g) + O(g)
