✦ Synopsis

The kinetics of the reaction of 0 atoms with NO2 was investigated in the temperature range 199-357 K. The value of the rate constant can be expressed by k, = (5.21 kO.50) x lo-'* exp [(202*27)lT] cm3 s-' (3~ error). At temperatures below 230 K, the formation of equilibrium concentrations of N204 and N203 affects the 0 atom decay. The values of the rate constants for the reactions of 0 atoms with Nz04 and N203 were estimated at 199 K to be smaller than k, by factors of at least 8 and 35, respectively.
