Several aspects of adsorption and reaction kinetics in catalysis over induced nonuniform surfaces are considered. They are discussed in terms of the surface electronic gas model, which accounts for the case of inhomogeneous surface. The adsorption equilibrium of gas mixtures was described, and adsorption isotherms were obtained. The reaction rate for the two-step sequence was deduced, and for that scheme the problems of optimum catalyst and metal-support interactions were considered. Structure sensitive and insensitive reactions with nonuniformly reactive adsorbates are also discussed in terms of the surface electronic gas model using the Polanyi parameter. The procedure for the rate law computation is given. Examples include a reaction graph with a pendent vertex and irreversible deactivation and reaction mechanisms with nonlinear elementary steps.
