✦ Synopsis

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 found k,,,, = (3.7 ? 0.7) x * s-'). The secondary reactions X + XNOz -+ X z + NOz ( X = Br, I) have been studied by mass spectrometry and their rate constants have been estimated from product analysis and computer modeling.

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-:
