Abstract: Nonstationary kinetic behaviour of a simple model mechanism (of an overall reaction A⇆R) with displacement adsorption (A + RS⇆AS + R, S being the catalyst active site) is analyzed. Examples of transient responses are presented that are typical for the mechanism with a displacement adsorption. However, in many cases mechanisms with direct and displacement adsorption cannot be distinguished by means of the transient response methods. An interesting relation between kinetics and thermodynamics in unsteady flow systems is described.
