The reaction between ozone and carbon monoxide was reinvestigated in the range of 80–160°C. The previously reported rate law − d [O 3 ]/ dt = k a [O 3 ][CO] + k b [O 3 ] 2 was confirmed and simulated using a mechanism based on an impurity‐initiated chain reaction. When the CO was sufficiently purified, k b tended to zero and k a reduced to the value expected for the thermal decomposition of O 3 . Subsequent reactions of O atoms with CO produced chemiluminescence which was used to measure k 3 for\documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm O}\,\, + \,\,{\rm CO}\,\,\mathop {\longrightarrow}\limits^{\rm 3} \,\,{\rm CO}_{\rm 2} \left( {^3 B_2 } \right) $$\end{document}as 10 −14.0±0.3 exp[−(1630 ± 325)/ T ] cm 3 molecule −1 s −1 . The implications of this are discussed.
