The volume profile of chemical reactions (Modern aspects of physical chemistry at high pressure : the 50th commemorative volume)

The Volume profile of a chemical reaction has the same significance to the high pressure investigator that the energy profile has for the kineticist. In some ways, it conveys more information. This paper discusses its general features and how it is determined, considers the simplest cases of concerted reactions, analyzes the meaning of "early" and "late" transition states, and weighs the possibility of pressure mediated changes in mechanism.
