The aim of this work is to describe the influence of electronic excitation of electrically neutral particles in chemically non-equilibrium five-component N{sub 2}/N{sub 2}{sup +}/N/N{sup +}/e{sup -} and O{sub 2}/O{sub 2}{sup +}/O/O{sup +}/e{sup -} ionized mixtures without magnetic field. Using the modified Chapman-Enskog method, the transport coefficients are found in the temperature range 500-50000 K for various mixture compositions. The flow conditions, where excitation of electronic degrees of freedom is of importance for the evaluation of transport properties are specified.
