Kinetics of the Reaction between Formyl Radicals and Atomic Hydrogen
J. Phys. Chem. 1987, 91, 692.
Abstract
The kinetics of the reaction of formyl radicals with atomic hydrogen was studied as a function of
temperature. The reaction was isolated for direct investigation in a tubular reactor coupled to a
photoionization mass spectrometer. Rate constants were obtained for the overall reaction H + HCO ->
products. They are 1.4E-10 (296 K), 1.3E-10 (350 K), and 0.96E-10 (418 K) cm3/molecule s. Estimated
error limits are ±30%. These measured rate constants are in close agreement with recently calculated
values obtained by Harding and Wagner using an ab initio potential energy surface for H2CO characterized
along the reactive pathways of this reaction.
