- Abstract
- The oscillatory behavior of the oxidation of carbon monoxide was experimentally studied in an attempt to further elucidate the reaction at low pressure. The phenomenon is observed as multiple explosions, and involve successive flashes of light accompanying the slow reaction in a static system, including over 450 flashes in one case. Electronicaly excited hydroxyl radicals (water impuity) and carbon dioxide have been identified as components of the emission. The phase difference between the two was seen to be negligible. The nature of the temperature and pressure changes during a cycle indicates that the oscillation is purely kinetic rather than thermokinetic. A procedure is presnted whereby sutained oscillations can be obtained for paticular P-T, vessel surface pretreatment and H2O-containing reactants.
