Dissociation of CO2 molecules in a wide temperature range

Abstract

Expressions are derived for the dissociation rate constants of molecules of carbon dioxide in the temperature range from 300 to 40000 K under both thermally equilibrium and nonequilibrium conditions. Under nonequilibrium conditions, the rate constants are represented as a two-temperature dependence (on the gas temperatureT and on the unified temperature Tvof all vibrational modes of CO2) and as a one-temperature dependence in which averaged vibrational nonequilibrium is included
