Abstract

The Rice-Ramsperger-Kassel-Marcus formations of unimolecular reaction rates have been applied to the processes C2H6 → 2CH 3, C2H5 → C2H4 + H and CH2OCH3→CH2O + CH3, various models being considered. For the C2H6 dissociation satisfactory agreement is obtained on the basis of two models; one involving softened vibrations, and one involving two active rotations in the activated complex, in both cases a correction being made for the centrifugal effect. For the C2H5 decomposition a model involving one active rotator in the activated complex and two active rotators in the energized radical leads to excellent agreement. For the CH2OCH3 decomposition good agreement was obtained on the basis of a model consisting of two active rotators in both the activated complex and the energized radical.
