## Abstract

Recent quantum dynamical calculations have shown that HO_{2} dissociates via isolated resonances, which have a distribution of rate constants that is statistical state-specific and well-described by the Porter-Thomas P_{E}(k) distribution. In the work presented here, this P_{E}(k) distribution is incorporated into RRKM theory to see how statistical fluctuations in state-specific rate constants affect the collision-averaged chemical activation rate constant k(ω, E) and the Lindemann-Hinshelwood thermal rate constant k_{uni}(ω, T) for HO_{2} dissociation. Both active and adiabatic treatments are considered for the K quantum number. The calculations suggest the effect of statistical state specificity should be detectable in measurements of k(ω, E) and k_{uni}(ω, T).
