We report a detailed dynamics and kinetics study of the title reaction over the range of translational energies 0.418 less than or equal to E-tr/kJ mol(-1) less than or equal to 62.760 by employing the quasiclassical trajectory method and a recently reported double many-body expansion potential energy surface for ground-state HO3. A comparison of the calculated thermal rate constants with the available experimental results is also presented.
