(b) True

(c) False

This question was addressed to me in homework.

Asked question is from Mechanisms of Catalyst Deactivation topic in portion Suspended Solid Reactors, Catalyst Deactivation, Diffusion and Reaction of Chemical Reaction Engineering

Answer 1

Right answer is (a) In parallel deactivation, the reactant produces a side product which deposits on the catalytic surface and deactivates it.

To explain I would say: A parallel deactivation is the one in which reactant A produces the product R and the poison P.

A  →  R + P↓
