✦ Synopsis

The bimolecular reactions in the title were measured behind shock waves by monitoring the 0-atom production in COS-02-Ar and CS2-02-Ar mixtures over the temperature range between 1400 and 2200 K. A value of the rate constant for S + O2 -+ SO f 0 was evaluated to be (3.8 2 0.7) x 10" cm3 mol-' s-' between 1900 and 2200 K. This was connected with the data at lower temperatures to give an expression k , = lO'OS5 To 52 cm3 mol-' s-' between 250 and 2200 K. An expression of the rate constant for CS2 + O 2 + CS + SOz was obtained to be k2' = exp(-32 kcal mol-'/RTj cm3 mol-' s-' with an error factor of 2 between 1500 and 2100 K.
