Recent experimental results on the thermal decomposition of N205 in N2 are evaluated in terms of unimolecular rate theory. A theoretically consistent set of fall-off curves is constructed which allows to identify experimental errors or misinterpretations. Limiting rate constants k o = "21 2.2 X lo-:
The equilibrium constant, K,, of the reaction NO2 + NO3 + M N z O ~ + M has been determined for a small range of temperatures around room temperature in air at 740 torr by direct spectroscopical measurements of NOz, NOS, and NzOs. At 298 K, K, was determined as (3.73 2 0.61) x lo-'' cm3 molecule-'.
The reactions Br + NO2 + M -+ BrNOZ + M (1) and I + NOz have been studied at low pressure (0.6-2.2 torr) at room temperature and with helium as the third body by the discharge-flow technique with EPR and mass spectrometric analysis of t h e species. The following third order rate constants were fou
The termolecular rate constant for the reaction C1 + NO, + M has been measured over the temperature range 264 to 417 K and at pressure 1 to 7 torr in a discharge flow system using atomic chlorine resonance fluorescence at 140 nm to monitor the decay of C1 in an excess of NO,. The results are ky = 9.
## Abstract The low‐pressure recombination rate constants of the reactions I + NO + M → INO + M (with 14 different M) and I + NO~2~ + M → INO~2~ + M (with 26 different M) have been measured at 330°K by laser flash photolysis. The collision efficiencies β~c~ are analyzed and compared with other ther
