Comments:
The errors quoted for Arrhenius parameters are the statistical errors, at the 1σ level, derived from the linear least-squares fit of the Arrhenius plot. The experimental systematic errors result from the error in pressure measurement (1%), flow measurement (1%), and temperature (0.5%), producing an overall error of 1.5%. The uncertainty in the preexponential factor is expressed as follows: A = (1.6 (+2.5/-1.0))x10-10 cm3 molecule-1 s-1.
