Kinetic studies of the reaction of the SO radical with NO2 and ClO from 210 to 363 KThe rates of the reactions of the SO radical with NO2 and ClO (significant in the upper atmosphere of earth and Venus) were determined in a discharge flow system near 1 torr pressure with detection of radical and molecular species using collision-free sampling mass spectrometry. The rate constants were obtained from the decay of SO radicals in the presence of an excess of NO2 and ClO. The NO2 reaction was examined between 210 and 363 K and found to be temperature invariant: SO + NO2 yields SO2 + NO; k1 = (1.37 + or - 0.10) x 10 to the -11th cu cm/s. In addition, the ClO reaction was observed to be independent of temperature between 248 and 363 K: SO + ClO yields SO2 + Cl; k2 = (3.22 + or - 0.48) x 10 to the -11th cu cm/s. A comparison was made with previous investigations of these reactions at room temperature and with other radical-radical reactions involving SO or ClO.
