Abstract

In this paper, simple analytical state-to-state rate coefficients for the dissociation–recombination and chemical exchange reactions are presented on the basis of kinetic theory in nonequilibrium excited diatomic gases. They take into account the excited vibrational and electronic states of the chemical species and are expressed according to the preferential character of the chemical reactions. Evolution of these rate coefficients varying according to the translational temperature, bringing into play molecules CO and C2, are discussed.
