Show Answer
Answer: (4)
Solution:
(A) Physisorption $=20-40 kJ / mol$ and
Chemisorption $=80-240 kJ / mol$
(B) Physisorption is multi-layered and
chemisorption is unimolecular layered.
(C) In heterogeneous catalysis, medium and catalyst are in different phases.
(D) Chromatography th uses adsorption to purify/separate mixtures.
