O + C2H4 -> CH3 + HCO


k = 1.25E+07 T^1.83 exp(-220 cal/mol /RT) cm3/mol s


SOURCE:
Rate expression is a fit to the 2-term expression of Klemm et al. (1990) for the overall rate coefficient multiplied by the 0.65 branching fraction to this channel. Baulch et al. (1992)recommend 0.60.
COMMENTS:
Related reaction is 285 O + C2H4 = H + CH2CHO.

Total rate constant for k(25) + k(285) is the same as the GRI-Mech 1.2 value.
