Temperature Dependence of the Rates of Addition of Oxygen Atoms to Olefins

Abstract

Relative rates of addition of oxygen atoms to several representative olefins have been measured at 25° and 125°C, and the ratios of the pre-exponential factors and differences in activation energies have been calculated from the mean values of the relative rate constants at the two temperatures. The results obtained show that the differences in reactivities are primarily due to differences in the activation energies while the pre-exponential factors remain approximately constant.
