Our understanding of catalytic reactions exists at various levels
which are mainly defined from detailed knowledge of reaction
mechanism. When viewed in terms of the stoi chiometric reaction
equation, most catalytic reactions are complex processes which
occur via a sequence of elementary (i. e. irreducible) steps, and
the elucidation ofthese elementary steps and the identification of
a rate determining step (if one exists) constitutes the traditional
approach to the problem of mechanism. The term "traditional" is not
used here in a pejorative sense since mechanistic knowledge of this
sort makes an important contribution to catalyst design,
improvement, and optimization. This is the field which is discussed
by Professor R. L. Burwell in Chapter 1 where the very wide range
of useful approaches and techniques is made apparent, even when one
is restricted to quasi-steady state conditions. Techniques which
depend on observations under non steady state conditions (i. e.
relaxation methods) have also been used in mechanistic studies,
increasingly so in recent years. This topic is discussed in detail
by Professor K. Tamaru in Chapter 2. At a deeper level of
understanding, one may seek to enquire how an elementary reaction
proceeds in terms of movement in a multicoordinate space where the
variables define atomic positions and energy. This is a problem of
great complexity even in relatively simple cases. Nevertheless,
despite the problems some progress is being made, and this and
allied topics are discussed in Chapter 3 by Professor G. L. Haller
and Dr. G. W. Coulston."
