C2H3 + O2 -> O + CH2CHO

k = 3.03E+11 T^0.29 exp(- 11 cal/mol /RT) cm3/mol s

SOURCE:: Mebel, A.M., Diau, E.W.G., Lin, M.C., and Morokuma, K. (1996) J. Am. Chem. Soc. 118, 9759.

COMMENTS:: Related reactions are 173 C2H3 + O2 = HCO + CH2O and 295 C2H3 + O2 = HO2 + C2H2.; Arrhenius graph for all channels of C2H3 + O2 is shown here.; The negative temperature exponent given in the Mebel et. al. article is a misprint; +0.29, the result actually derived by these authors, was adopted for the version 3.0 expression for this reaction.
