Kinetics of Ozone Formation in the Pulse Radiolysis of Oxygen+Ethylene Mixtures
(Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (5), 1973) Bevan, P. L. T.; Johnson, G. R. A.
Pulse radiolysis of O2+ C2H4 mixtures has been used to determine the rate constant of the reaction O + O2+ M → O3+ M (M = C2H4) the values, obtained from the kinetics of O3 formation and from the dependence of the O3 yield on C2H4 concentration, being 6.5 ± 0.7 × 10–32 and 5.3 ± 0.5 × 10–32 cm6 molecule–2 s–1, respectively. Competition studies, in the absence and presence of SF6, show that C2H4 depresses the primary yield of O atoms from pulse-irradiated O2, the maximum depression by C2H4 being the same as that by SF6.
