Chapter 10, Problem 99E

One reaction involved in the sequence of reactions leading to the destruction of ozone is
${\text{NO}}_{\text{2}}\left(\text{g}\right)\text{+O}\left(\text{g}\right)\to \text{NO}\left(\text{g}\right){\text{+O}}_{\text{2}}\left(\text{g}\right)$
Calculate $\Delta r{H}^{°}$ for this reaction by using the thermodynamic data in Appendix D. Use your $\Delta r{H}^{°}$ value, plus data from Table 10.3, to estimate the nitrogen-oxygen bond energy in $N{O}_2$ . (Hint: The structure of nitrogen dioxide, $N{O}_2$ , is best represented as a resonance hybrid of two equivalent Lewis structures.)
