Pressure Region

A generalized equation for the unimolecular rate constant in the low-pressure region is used to estimate the effect of mode separation on decomposition rate. The controlling factor in determining the degree of ergodicity of the dynamics, and hence the decomposition rate, is the number of mode sets between which energy exchange is frozen. The distribution of modes within the sets is not crucial.
