Fast variable dynamics, liquid phase chemical

IV. THE FAST VARIABLE DESCRIPTION OF LIQUID PHASE CHEMICAL DYNAMICS... 

We next quickly review, from the standpoint of the recent literature [6,11-17], our fast variable theory of liquid phase chemical processes [19-26]. This theory is designed to deal relatively realistically with the fast variable physics that is the signature of liquid phase chemical dynamics. 

We have emphasized in this chapter that Arrhenius principle implies that liquid phase chemical reactions occur in a nonclassical fast variable near sudden limit timescale regime rather than in the slow variable near adiabatic regime of standard irreversible statistical mechanics. Despite this, the traditional theories of liquid phase reaction dynamics [7-10] are of the slow variable type. 

It reviews our fast variable theory of liquid phase dynamics [19-26] placing it in its context within statistical mechanics, and also relating it to the recent literature [6,11-17,27,28]. This theory was motivated by and is in accord with the familiar Arrhenius principle that only atypically fast reactant molecules have sufficient energy to surmount chemical activation barriers.
