✦ Synopsis

A generalized isothermal effectiveness factor correlation has been proposed for catalytic reactions whose intrinsic kinetics are based on the redox model. In this correlation which is exact for asymptotic values of the Thiele parameter the effect of the parameters appearing in the model, the order of the reaction and particle geometry are incorporated in a modified form of Thiele parameter. The relationship takes the usual form: 9= tanh 4% 4* and predicts effectiveness factor with an error of less than 2% in a range of Thiele parameter that accommodates both the kinetic and diffusion control regimes.

A model for the collision rate of an impurity ion in a plasma is formulated by extending a corresponding model for velocity and electric field correlation functions. All dynamical effects of the plasma are represented by its electric field at the impurity, which is then given a simple stochastic des
