The interaction between vibrational relaxation and chemical processes is significant in many gas dynamic environments such as high‐enthalpy air flows. Extending a work of Marrone and Treanor [1] the influence of the vibrational excitation is examined not only on dissociation reactions, but also on exchange reactions. A synthetic cross section is chosen which allows to obtain a relatively simple form of a coupling factor between experimentally measured rates, valid only in thermal equilibrium, and theoretically derived rates, valid also in strong thermal‐nonequilibrium.
