The rate of the reaction (1) NO + HOz + OH + NO2 was determined in an isothermal discharge flow reactor with a combined ESR-LMR detection under pseudo-first-order conditions in HOz. The rate constant was identical in experiments with two different HOn sources: F + H202 and H + 0 2 + M. The absolute

β¦ Synopsis
The high-temperature oxidation of formaldehyde in the presence of carbon monoxide was investigated to determine the rate constant of the reaction HOZ + CO = CO:! + OH (10). In the temperature range of 878-952Β°K from the initial parts of the kinetic curves of the HOz radicals and CO, accumulation at small extents of the reaction, when the quantity of the reacted formaldehyde does not exceed lo%, it was determined that the rate constant klo is k l o = (1.7 f 0.5) X 10-'"exp[ -(23,000 + 3000/RT)] cm3/molec.sec A computer program was used to solve the system of differential equations which correspond to the high-temperature oxidation of formaldehyde in the presence of carbon monoxide. The computation confirmed the experimental results. Also discussed are existing experimental data related to the reaction of HOt with CO.
