SHOCK TUBE DECOMPOSITION OF NITROUS OXIDE

Abstract

The thermal decomposition of nitrous oxide was studied in the temperature region from 1500K to 2200K. Shock tube techniques, employing the region behind the initial shock wave, were used. Because of the exothermic nature of the decomposition of nitrous oxide it was necessary to study mixtures of nitrous oxide in an excess of diluent. The results obtained with nitric oxide as a diluent indicate that the reaction is bimolecular. The rate constant derived from these experiments is in excellent agreement with the rate constant obtained by other investigators at lower temperatures. The data obtained with argon, oxygen, or air as diluents indicate that the decomposition is bimolecular at low concentrations and becomes monomolecular at higher concentrations. The activation energy was found to depend on concentration. The maximum activation energy occurs at the highest total concentration, about 0.00015 moles/cc, and was determined to be 56,000 cal/mole.
