Chapter 8, Problem 56PS

Oxygen atoms can combine with ozone to form oxygen:

O₃(g) + O(g) → 2 O₂(g)

${\Delta }_r{H}^{\circ }$ = −392 kJ/mol-rxn

Using ${\Delta }_r{H}^{\circ }$ 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?
