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.
