Question
Which among the following statement is false?
A. Chemisorption is reversible in nature
B. Particle size of adsorbent will not affect the amount of adsorption
C. Increase of pressure increases amount of adsorption
D. Increase of temperature always decreases the amount of adsorption
A. Chemisorption is reversible in nature
B. Particle size of adsorbent will not affect the amount of adsorption
C. Increase of pressure increases amount of adsorption
D. Increase of temperature always decreases the amount of adsorption
Answer: Option B
:
B
A.It is irreversible in nature because of the formation of new bonds.
B.Surface area of a powdered solid adsorbent depends on its particle size. Smaller the particle size, greater is its surface area and hence more is the extent of adsorption.
C.Correct statement
D.In case of chemisorption isobar, it first increases and then decreases with increase in temperature.
