β¦ Synopsis
Absolute rate paramctcrs wcrc mtiasured for the gas phase reactions of CBr(% '11) produced in the flash photolysis of CHBr3 with a variety of paraffins, olcfins. 0:: and NO. The rate of cyclaaddition to unsaturated bonds increases with alkyl substitution, pointing to the clcctrophilic nature of CBr. In comparison with published data on CC1 and CH the reactivity follows the trend CBr = CCI < CH.

## Abstract Arrhenius parameters for the decomposition reactions of various alkoxy radicals are evaluated. The recommended values for __tert__βbutoxy radical decomposition reaction are log __A__ (s^β1^) = 14.1, __E__~__a__~ = 15.3 kcal/mol. magnified image The parameters give reasonably selfβconsis
The preceding paper describes the reanalysis by Kerr and Parsonage (following discussions with one of us, H.W.S.) of some of our published work. We are grateful to Dr. Kerr for communicating their conclusions to us. We agree in principle with their analysis, and the present communication is to repor
The relative rate constants for the hydrogen atom abstraction by CCl&H=CH. radical from CHtC12, CHC13, CHaCOCHa, CH&N, C C ~H ~C H ~, C6H50CH3, CH3CH0, and CHIOH in the liquid phase at 20Β°C have been measured. It was shown that these reaction rate constants are correlated by the two-parameter Taft e
Rate constants have been measured in aqueous solutions for the reactions of the carbonate radical, COs'-, with several saturated alcohols and one cyclic ether as a function of temperature. Arrhenius pre-exponential factors ranged from 2 X lo8 to 1 X lo9 e mol-' s-l and activation energies ranged fr
A laser-flash photolysis/UV absorption technique has been used to study the temperature dependence (from T Ο 300 -470 K) of the self-reaction kinetics of representative primary, secondary, and tertiary β€-hydroxyperoxy radicals: The following Arrhenius expressions were derived for the rate coefficie
