✦ Synopsis

The decay of SO generated in the reaction 0 r0CS-r CO+ SO in the absence of O1 has been studied at 298 K from 2 to 8 Torr, using a tubular Row reactor coupled to a mass spectrometer. The products of the decay of SO are S. SO:. S20. and (SO),. The kinetics of tile decay of SO could be accounted for on the basis of the mechanism: SO-SO + hl+ ISOl~+hl(3~, SO+SO+S0~+S 141. so+(so12+ SO>+S:O 151. and SO+products 16). where the latter represents either a wall reaction or a slow bimolecuiar reaction with OCS. On the basis of computer modeling we derire k3 = 1.6x 10"cmLmolV2 -' 5 and k5 = Z x lO'"cm mol-' s-'.
