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 I or greater. Over the indicated temperature range, the data could be fit to the simple Arrhenius expression as k(DMS) = (9.96 +/- 3.61) x 10(-11) exp (-(7309.7 +/- 1098.2)/T) cm(3)/(molecule center dot s). A compared investigation of the reaction. between ozone and ethene had a k(C2H4) value of (1.35 +/- 0.11) x 10(-18) cm(3)/(molecule center dot s) at room temperature.
