The rate coefficient of the reaction H + CO z ~ CO + OH (1) was measured using OH concentration measurements in shock-heated N20-H2-CO 2 mixtures and through the inhibiting effect of CO 2 on methane ignition. For 2170 < T < 3150 K the two methods give concordant results and imply k I = 2.0 ร 1014exp

โฆ Synopsis
Spectral intensities from the chemiluminescent reaction CO + O --* CO2 + hv have been measured in the range 2600-7000 /k from reacting mixtures of H2-O2-CO-CO2-argon, shock heated in a shock tube to temperatures of 1300 and 2700K. Integrals of the photon production rate yield an overall rate coefficient -to = 6.8 ( +_ 0.6) x 105 exp(-1960/73 cm 3 mole-~ s-~. Extrapolated to 300K, this rate coefficient is in excellent agreement with the room temperature measurements of Pravilov.
