The intrinsic selectivity of a heterogeneous catalyst may be modified by addition of poisons when a different number of catalytic sites are occupied by various reacting species. We extend here a model of Herington and Rideal to account for modification of intrinsic selectivity of catalytic first ord

The selectivity of two first-order, parallel reactions, one reversible and one irreversible, can be altered substantially by the presence of an intraparticle diffusion resistance. At very large resistances, the relative selectivity approaches an asymptotic limit which depends on the kinetic, transpo
