Conditions leading to an explosive reaction of carbon monoxide and oxygen in the presence of small amounts of water have been examined at temperatures of 973 and 1048 K. Carbon monoxide and water were formed in the presence of oxygen by reaction with a thin film of carbon deposited on a quartz vessel. The carbon provided a reactive and reproducible surface, giving aconsistent rate of termination and thus allowing a quantitative descriptionof the conditions at the explosion in the region of the first limit. Calculations of the rates of the various branching and termination reactions at the onset of the explosion showed that the simple mechanism described earlier was still adequate to explain the reaction at temperatures up to 1050 K. From experiments with inert gases the transition from the first explosion limit to the region of the second explosion limit was demonstrated.
