Abstract
The absolute rate constant of the reaction of O(^3^P) with toluene was measured by the microwave dischargeβfastβflow method to obtain k~T~ = 10^9.7β2.7/2.303__RT__^ l./moleΒ·sec at 100β375Β°C. This was in good agreement with the rate constant calculated from the combination of the relative rate constant obtained by Jones and Cvetanovic with the recently determined absolute rate constants of the reaction of O(^3^P) + olefins. The extrapolation of the above Arrhenius plot to 27Β°C was also in good agreement with the absolute value of k~T~ = 4.5 Γ 10^7^ l./moleΒ·sec determined recently by Atkinson and Pitts at 27Β°C. The rate constant of the reaction of chlorobenzene with O(^3^P), obtained at 238Β°C as 10^8.3^ l./moleΒ·sec by a competitive method, was smaller than k~T~ by a factor of about two at the same temperature.

the formation of higher oxides of chlorine such as Cl 2 O 4 , Cl 2 O 6 , and Cl 2 O 7 has been observed [5 -8]. The reaction mechanisms are not understood but may involve the formation of ClO 3 which has recently been observed in an inert matrix [9]. In these systems, ClO 3 can be formed via the add
The rate constant for the reaction of O(") with H202 was measured as a function of temperature and the [H202]0/[0]0 ratio. The numerical solution of the appropriate rate equations was used to arrive a t a mechanism which adequately describes our results and the rather divergent data in the literatur
