Synopses & Reviews
This book contains the proceedings of a workshop on interface phenomena with special emphasis on kinetics of interface reactions. Each of the three days was devoted to a specific topic of some controversy which was highlighted by invited speakers representing opposing views. The comments of the session chairman summarize the intense discussions and point out directions for further research. More specifically, the first day's discussion centered on "Adsorption-Desorption Kinetics: Dynamics versus Thermodynamics", with invited contributions by D. Menzel and W. Brenig, and a summary by H.J. Kreuzer. The second day was devoted to "Precursors: Myth or Reality?", with major papers by W.H. Weinberg and D. Auerbach. The active discussions were summarized by T. Engel. On the third day, we tried to map out a strategy to study "Kinetics of Phase Transitions at Surfaces", with main contributions by K. Heinz and J.D. Gunton, summarized by P.H. Kleban. An overview and outlook was given on the last day by P. Estrup. In all, the proceedings contain 6 invited lectures, summaries and a dozen contributed papers.
Synopsis
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.
