The reaction: A → products can be described by a zero-order rate law. a) Derive the relationship between the concentration of A at the surface of a non- porous catalyst particle (CA,s) and that in the bulk (CA,b). Define X for such a system and rewrite your relationship as CA,s = f(CA,b, x). b) Explain what happens as X increases from near 0 to X> 1 for this system, what type of values do you get for CA,s, and what causes this behavior?
