Problem 2(8pts). You are running a reaction in a packed bed reactor containing porous pellets with catalyst inside the pellets pores. Your reactor setup consists of a certain molar flow rate of your reactant that is co-fed with an inert gas. You run out of your first inert gas, Ar, so you replace it with N2, at the same flow rates. You do not see any change in the conversion through your reactor. Your colleague tells you that this means you must not be diffusion (internal mass transport) limited. Discuss conditions where they may be right (or wrong), using what we learned in class. Be clear about your assumptions
