The reaction between ozone and carbon monoxide was reinvestigated in the range of 80-160Β°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

β¦ Synopsis
19 torr and a flow rate of 1.4 x 10'" was 2.71 x 10" atoms of C per cm" per sec. This is 1.8 per cent of the rate of ablation of graphite with oxygen for similar reaction conditions. The effect of pressure, flow and temperature on the rate of reaction is presented. Correlation is made with kinetic theory calculations and with studies made by other workers at lower temperatures.
Comparison is made with the oxygen reaction.

## Abstract The reaction of hydrogen atoms with diazomethane was used as a source of methyl radicals to study the reaction of oxygen atoms with methyl radicals. This investigation verifies directly the earlier results that formaldehyde is a major product and that the rate constant is greater than 3
