B
Magnitude of chemisorptions decreases with rise in temperature while physisorption increases with rise in temperature.
C
Chemisorption is irreversible and physisorption is reversible.
D
In physisorption activation energy is low while in chemisorptions it is high.
Answer
Magnitude of chemisorptions decreases with rise in temperature while physisorption increases with rise in temperature.
Explanation
Solution
Chemisorptions increases and physisorption decreases with rise in temperature.
