✦ Synopsis

A new technique is described for quantitative measurement of the conditions of reactant concentration at ignition in mixtures of carbon monoxide and oxygen. A thin film of carbon covering the surface of a quartz reaction vessel reacted with oxygen to form carbon monoxide and small quantities of water. Explosions were observed above 900 K over the pressure range 15-100 torr with ratios of CO/Oz far below those hitherto explored. The onset of explosion was favored by the addition of hydrogen, methane, and water and was inhibited by the addition of inert gases. A simple mechanism predicts the occurrence of an explosion over a wide range of product composition and total pressure.

The reaction between ozone and carbon monoxide was reinvestigated in the range of 80-160°C. The previously reported rate law -d[O,l/dt = k.[o,][Co] + k,[0,l2 was confirmed and simulated using a mechanism based on an impurity-initiated chain reaction. When the CO was sufficiently purified, k, tended

The reaction of carbon monoxide with ozone was studied in the range of 75-160OC in the presence of varying amounts of COZ and, for a few experiments, of 0 2 . At room temperature the reaction was immeasurably slow, but in a flow system it showed chemiluminescence with undamped oscillations. In a sta

The so.called low pressure glow and explosion limits of the water-cataiysed reaction between carbon monoxide and oxygen have been studied using a photomultiplier to obtain light intensity/time graphs. The results show no sign of a glow limit, and little discontinuity at the explosion limit. The effe
