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) × 10^-11 exp (-(7309.7 ± 1098.2)/T) cm^3/(molecule.s). A compared investigation of the reaction between ozone and ethene had a kC2H4 value of (1.35 ± 0.11) × 10^-18 cm^3/(molecule.s) at room temperature.展开更多
