Dissociation of $\mathrm{CO}_2$ molecules in a wide temperature range

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 temperature $T$ and on the unified temperature $T_V$ of all vibrational modes of $\mathrm{CO}_2$) and as a one-temperature dependence in which averaged vibrational nonequilibrium is included.
