Book Description
This book contains the proceedings of the first Workshop on Interface Phenomena, organized jointly by the surface science groups at Dalhousie University and the University of Maine. It was our intention to concentrate on just three topics related to the kinetics of interface reactions which, in our opinion, were frequently obscured unnecessarily in the literature and whose fundamental nature warranted an extensive discussion to help clarify the issues, very much in the spirit of the Discussions of the Faraday Society. Each session (day) saw two principal speakers expounding the different views; the session chairmen were asked to summarize the ensuing discussions. To understand the complexity of interface reactions, paradigms must be formulated to provide a framework for the interpretation of experimen tal data and for the construction of theoretical models. Phenomenological approaches have been based on a small number of rate equations for the concentrations or mole numbers of the various species involved in a par ticular system with the relevant rate constants either fitted (in the form of the Arrheniusparametrization) to experimental data or calculated on the basis of microscopic models. The former procedure can at best serve as a guide to the latter, and is, in most cases, confined to ruling out certain reaction pathways rather than to ascertaining a unique answer.

Book Description
The first Workshop of Interface Phenomena concentrated on just three topics related to the kinetics of interface reactions: (1) adsorption-desorption kinetics, (2) precursors, (3) kinetics and phase transitions. The adsorption and desorption processes themselves are to be understood as surface bond making and breaking mechanisms, respectively. If the energy transfer is fast enough, then these processes can be understood in terms of thermodynamic arguments such as formulated in transition state theory. However, in most situations such as simple treatment is not sufficient and the details of the microscopic dynamics must be invoked. Unfortunately, this point is very frequently overlooked in the analysis of kinetic data of gas-surface reactions, leading to rather murky discussions in the literature. The phenomenological analysis of surface reactions in terms of kinetic rate equations quite often has to invoke precursor states as reaction intermediates to fit experimental data. However, because such an analysis rarely leads to a unique answer, independent evidence must be brought forward if precursors in a given reaction are to be accepted as more than just mythical mis-fits. The equilibrium properties of surface phase transitions have been studied for many decades, and they exhibit a wealth of fascinating detail. The exploration of their kinetics, on the other hand, had to await the advent of time resolved surface analysis techniques. In particular, video-LEED has made it possible to study kinetics of surface reconstruction.
