Abstract
The cooperative mechanism for dissociative chemisorption is discussed using a very simple, 'all or none' model. This suffices to recover the essential aspects of the equilibrium behavior. In particular it is pointed out that the mechanism is equally applicable either to molecules which dissociate already at very low temperatures or those at which low temperatures are physisorbed. A similar mechanism can operate for interconversion of two adsorbed species. The physical assumptions of the model are discussed.
