Estimation of Rate Constants of Thermal Dissociation of Two-Atomic Compounds and Three-Particle Association in the Temperatures Range from 500 to 5000 K

Abstract

Based on an analysis of the approximation dependences on the dissociation energy for rate constants of thermal dissociation of two-atomic compounds and three-particle association, constructed by the least-squares method, an analytical expression for their estimation is derived. It is shown that the calculated and approximation dependences of the published data almost coincide with each other. The maximum disagreement of the dependences does not exceed 2% for the temperature range from 500 to 5000 K.
