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
## Abstract The Arrhenius parameters for the reactions equation image and equation image have been measured. Reaction (2a) was generated and studied by the photolysis of tetrachloromethane in the presence of trichlorosilane and reaction(2b) by the photolysis of 1,1,1,βtrichlorotrifluoroethane i
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
Rate constants have been determined for the reactions of SO4with a series of alkanes and ethers. The SO, radical was produced by the laser-flash photolysis of persulfate, SZO: -. For methane, only an upper limit of 1 x lo6 M-' s-\* could be determined. For ethane, propane, and 2-methylpropane, rate
