Estimate the average bond energy in O₃(g) from the structure and data in Table 10.3. Compare this result with that of Exercise 35.

Table 10.3

Exercise 35

The conversion of O₂(g) to O₃(g) can be accomplished in an electric discharge, 3 O₂(g) → 2 O₃(g). Use a bond dissociation energy of 498 kJ mol^–1 for O₂(g) and data from Appendix D to calculate an average oxygen-to-oxygen bond energy in O₃(g).
