Replacement of N 2 by CO in H 2 + 02 + N 2 mixtures undergoing slow reaction at 500Β°C causes a marked increase in the reaction rate and a decrease in the induction period, expressed as the time to half maximum rate. A detailed interpretation using a computer treatment gives k24/klo 1/2 = 0.42 Β± 0.03

β¦ Synopsis
The molecular-modulation-UV/visibleabsorption+ectroscopy technique has been used to investigate the simultaneous time. resolved behaviour of10 and HO2 produced by the pbotolysis of O3 in the presence of CH30H, Iz, O2 and Ar. This has enabled a direct measurement of the rate coefficient for the reaction 10+H02+HOI+0, IO be made at 760 Torr and 289 K. The value obtained was k5= (6420.7) X lo-" cm3 molecule-' s-l.

The kinetics and mechanism of the reaction Cl Ο© HO 2 : products (1) have been studied in the temperature range 230-360 K and at total pressure of 1 Torr of helium using the discharge-flow mass spectrometric method. The following Arrhenius expression for the total rate constant was obtained either fr
The rate constant for the reaction of the hydroxyl radical with l,l, 1-trichloroacetaldehyde has been determined at 298 f. 2 K. Rate data were obtained at atmospheric pressure by a relative rate method. The rate constant was also measured at lower pressures (l-3.4 Torr) using the discharge flow tech
Rate constants for the reactions of 0 3 and OH radicals with furan and thiophene have been determined at 298 f 2 K. The rate constants obtained for the 0 3 reactions were (2.42 f 0.28) X 1O-lS cm3/molec.s for furan and <6 X cm3/molec-s for thiophene. The rate constants for the OH radical reactions,
