✦ Synopsis


The gas phase reaction of NzOs with water vapor was investigated in a 17.3-m' Teflon lined chamber. Temporal concentration profiles for ozone, total nitrogen oxides, and nitrogen dioxide were measured. Concentration profiles for N2OS and HNO, were calculated from a combination of measurements of nitrogenous species. A kinetic mechanism with an adjustable value for the rate constant of NzOs + H,O was used to model the experiments. From this analysis an upper limit value of k s 4 x 1 0 ~ ' ppm min-' for the gas phase reaction N,O, + HzO + 2HNOi was derived.

Transition states for the two probable pathways for the gas-phase hydrolysis of hydrogen isocyanate have been determined using the MIND013 method. Activation barriers obtained showed that the one-step mechanism is preferred to the two-step mechanism involving an intermediate. It was shown that the r
