ON THE APPLICATION OF MEAN-VALUE THEOREM TO REACTION-KINETICS OVER INHOMOGENEOUS SURFACES

The application of a common mean-value theorem for the description of kinetics of heterogeneous catalytic reactions over inhomogeneous surfa ces is discussed. Being mathematically correct for integration of mult iple integrals, the mean value theorem can provide a correct value of reaction rate for a particular set of parameters, but physical reasons of its application are doubtful, as it obviously contradicts the kine tic regularities. As an example, the kinetics of a two-step sequence o n an inhomogeneous surface is discussed.
