Rate Constant for the reaction of Hydroxyl Radical with Formaldehyde over the Temperature Range 228-362 K
J. Chem. Phys. 1980, 73, 2254.
Abstract
Absolute rate constants for the reaction OH + H2CO have been measured over
the temperature range 228-362 K using the flash photolysis-resonance fluorescence
technique. The results were independent of variations in [H2CO], total pressure
[Ar] and flash intensity (i.e., initial [OH]). The rate constant was found to be
invariant with temperature in this range, the best representation being
k(A)=(1.05±0.11)E-11 cm3/molecule s where the error is two standard
deviations. This result is compared with previous absolute and relative
determinations of k(A). The reaction is also discussed from a theoretical point
of view.
