If there 1s both internal and external resistance to the transfer of heat and matter to a catalytic pticle some mterestmg combmatlons of effects may arise Since multiple steady states can be obtained when only one of the resistances IS considered, there IS a range of parameters for which five steady

✦ Synopsis
The equations for isothermal diffision and pth order reaction in a porous slab are integrated and the results presented in a series of araphs. The asymptotic relations and use of the graphs are discussed.

It is shown how upper and lower bounds to the effectiveness factor may be obtained by variational methods. The formulae are developed to be capable of handling mass transferresistance at the surface of the catalyst particle, a diffusion coefficient which depends upon position in the particle, and a
