The production of atomic deuterium and its reaction with ethylene.

Since the turn of the century chemical kinetics, the study of the rate of chemical reactions, has become one of the major divisions of physical chemistry. In the course of study many reactions it became apparent that the order of the reaction could not always be predicted from the Stoichiometric equation. This was due to the fact that reactions often occur in stages, although the stages may succeed one another so rapidly that it appears that a simple process is taking place
