The genera1 criterion for the importante of pore diffusion with reaction in porous solids as developed by Weisz and Prater is one of the most useful practical results of the effectiveness factor concept. This criterion uses only observable quantities and so can often be easily estimated. However, it
The steady state diffusion of gases through capillaries or through the pores of a solid when fusion, bulk flow of the gases is free to the total pressure in the system is constant is considered. I t is shown that the ratio of the molar occur, but in the present situation diffusion rate of the lighte
