A novel concept of effectiveness factor dependence on the length of a catalyst particle is suggested. Such behavior emerges in sufficiently long catalysts when an inhomogeneous state is established in the uniformly exposed particle. The source of instability considered here is an endothermic reaction with reactant inhibition (e. g. a Langmuir-Hinshelwood expression). The asymmetry results from the large thermal to mass diffusivities ratio. The possible steady state bifurcation diagrams and the corresponding sets are studied analytically.
