Oxygen atoms can combine with ozone to form oxygen: Using r H and the bond dissociation

Question:

Oxygen atoms can combine with ozone to form oxygen: Os(g) + O(g) 2 O2(g) = -392 kJ/mol-rxn

Using Δ_rH° 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?

Data given in table 8.8
