Notes:
The rates of several novel elementary reactions involving ClO, BrO and SO free radicals in their ground states were studied in a discharge-flow system at 295 K, using mass spectrometry. The rate constant k2 was determined from the decay of SO radicals in the presence of excess ClO radicals: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} {{\rm SO} + {\rm ClO} \to {\rm SO}_{\rm 2} + {\rm Cl;}} & {k_{\rm 2} = (2.3{\rm } \pm {\rm 0}{\rm .6}) \times 10^{ - 11} {\rm cm}^3 \sec ^{ - 1} } \\ \end{array}$$ \end{document}The SO + OClO overall reaction has a complex mechanism, with the primary step having a rate constant k5 equal to (1.9 ± 0.7) × 10-12 cm3 sec-1: \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm SO} + {\rm OClO } \to {\rm SO}_{\rm 2} + {\rm ClO} $$\end{document}A lower limit for the rate constant of the rapid reaction of SO radicals with BrO radicals was determined: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} {{\rm SO} + {\rm BrO} \to {\rm SO}_{\rm 2} + {\rm Br;}} & {k_{17} } \\ \end{array} \ge 4 \times 10^{ - 11} {\rm cm}^3 \sec ^{ - 1} $$\end{document}
