Temperature dependence of the absolute rate constant for the reaction of ozone with dimethyl sulfide.

Absolute rate constants for the reaction of ozone with dimethyl sulfide (DMS) were measured in a 200-L Teflon chamber over the temperature range of 283-353 K. Measurements were carried out using DMS in large excess over ozone of 10 to 1 or greater. Over the indicated temperature range, the data could be fit to the simple Arrhenius expression as kDMS = (9.96 +/- 3.61) x 10(-11) exp (-(7309.7 +/- 1098.2)/T) cm3/(molecule x s). A compared investigation of the reaction between ozone and ethene had a kC2H4 value of (1.35 +/- 0.11) x 10(-18) cm3/(molecule x s) at room temperature.
