CO/sub 2/ dissociation is studied in a plasma. Energetically the most efficient mechanism is dissociation through vibrationally excited states of the reactants; this pathway is taken in nonequilibrium rf and microwave discharges. The rate constant for the process is determined by studying the population of the highly excited states of the antisymmetric vibrational band; V--V, V--V', and V--T relaxation and reactions are taken into account. The energy balance in the antisymmetric and symmetric modes is used to find the dependence of the efficiency on the degree of ionization and the normalized power input to the discharge. The calculated results are compared with experimental data for rf and microwave discharges. These results can be used to predict optimum operating conditions for nonequilibrium plasma devices.
