Question

The variation of Chemisorption with Pressure is ____

(a) Chemisorption increases with increase in pressure

(b) Chemisorption decreases with increase in pressure

(c) Chemisorption increases with decrease in pressure

(d) Change of pressure has no effect on Chemisorption

I got this question in quiz.

I would like to ask this question from Packed Bed Catalytic Reactor topic in chapter Packed Bed Catalytic Reactor, Fluidised Bed and Transport Reactors of Chemical Reaction Engineering

Answer 1

Correct answer is (d) Change of pressure has no effect on Chemisorption

For explanation I would say: Chemisorption increases with increase in temperature, but change in pressure has no effect. The chemical adsorption is irreversible.
