Steady state dissociation of shock heated HF, HCl, and CO in excess Ar

Abstract

The steady state dissociation rate constants of shock heated HF,HCl, and CO in the presence of large excess of Ar are calculated, assuming that dissociation can occur from all the vibrational levels, at several temperatures and compared with experimental results. Both the truncated harmonic oscillator (THO) model and Morse oscillator (MO) model are considered. Both the models fit the dissociation rates satisfactorily in the temperature ranges considered. The results are in accord with a ’’weak bias’’ mechanism and large depletion in the higher vibrational levels.
