Component A is converted into compound B on the active sites within a porous catalytic particle manufactured in the shape of spheres of radius R. Disappearance of A occurs as a zero-order reaction with a rate constant where a is the available catalytic surface area per unit volume of catalyst. In terms of an "effective diffusion coefficient", Da, the concentration of A on the surface of particles Cas, the reaction rate constant ka, and the particle radius R, deve ka, lop expressions for: a. The concentration profile for compound A within the catalyst b. The molar flux for compound A at the surface of the particle c. The average concentration of compound A within the particle d. The rate of disappearance of compound A in the catalyst particle
