Reaction of carbon monoxide with ozone and oxygen atoms

摘要

AbstractThe reaction between ozone and carbon monoxide was reinvestigated in the range of 80–160°C. The previously reported rate law −dO3/dt=kaO3CO+kbO32was confirmed and simulated using a mechanism based on an impurity‐initiated chain reaction. When the CO was sufficiently purified,kbtended to zero andkareduced to the value expected for the thermal decomposition of O3. Subsequent reactions of O atoms with CO produced chemiluminescence which was used to measurek3fordocumentclass{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±0.3exp−(1630 ± 325)/T cm3molecule−1s−1.
