摘要：
By means of an analysis of currently available experimental data and theoretical models, expressions for the dissociation rate constant k0 are obtained for thermal equilibrium conditions. These expressions are necessary for describing the molecular dissociation process under both thermal equilibrium and non-equilibrium conditions in the gas. k0 values are presented for the O2, N2, NO, CO, CN, and C2 molecules at temperatures from 300 to 40,000 K, and their errors are estimated.
