Abstract

One of the most challenging problems in physical chemistry is the study of molecular processes on solid surfaces and chemisorption theory is part of this study. It is sometimes convenient to distinguish three situations in chemisorption:
  1. (a)

    the admolecule coverage is self-limiting so that well-defined overlayers are formed,

     
  2. (b)

    it is not, and there is continued attack on the metal to build up a reaction product as a new phase at the gas/metal interface,

     
  3. (c)

    the admolecule is decomposed at the metal surface.

     
Often the distinction between (a) and (b) will be a matter of temperature only ; the chalcogens form well-defined overlayers on Ni, but they corrode the metal at high temperatures.
