O CIO and its Reverse Reaction, Cl

As shown in Fig. 11, O + CIO can directly form OCIO and ClOO intermediates, the latter dissociates to Cl + O2. The isomerization from OCIO to ClOO needs a very high barrier, 63.3 kcal/mol it is not crucial to the measured kinetics of these reactions. The comparison of the total rate constants with experimental data is shown in Fig. 27. The results show that O + CIO - Cl + 02 channel is pressure independent and dominant formation of OCIO is pressure dependent and has some contribution to the total rate constants at lower temperatures and higher pressures as shown in the figure. The low- and high- pressure rate constants for the reactions. 

In addition, we also calculated the reverse rate constants of reaction (11 b), forming stabilized ClOO by collisional deactivation the results are in reasonable agreement with experimental values as shown in Fig. 28. The low- and high- pressure rate constants for this process can be expressed as
