Physical Adsorption: Incorrect Statement
Physical adsorption, also known as physisorption, is a type of adsorption that occurs due to weak van der Waals forces between the adsorbent and adsorbate molecules. It is a reversible process where the adsorbate molecules are held onto the surface of the adsorbent by weak intermolecular forces.
The incorrect statement about physical adsorption is:
A) It is usually monolayer
The correct statement is:
A) It can form monolayer or multilayer adsorption depending on the conditions of adsorption.
Explanation:
Physical adsorption is characterized by the formation of a thin film of adsorbate on the surface of the adsorbent. This film can be either monolayer or multilayer depending on the conditions of adsorption. The factors that affect the type of adsorption include temperature, pressure, surface area, and nature of the adsorbent and adsorbate.
Monolayer adsorption occurs when the adsorbate molecules form a single layer on the surface of the adsorbent. This type of adsorption is usually observed at low temperatures and low pressures. Multilayer adsorption occurs when the adsorbate molecules form multiple layers on the surface of the adsorbent. This type of adsorption is usually observed at high temperatures and high pressures.
Conclusion:
Physical adsorption is a reversible process that involves weak van der Waals forces between the adsorbent and adsorbate molecules. It can form monolayer or multilayer adsorption depending on the conditions of adsorption. The incorrect statement is that physical adsorption is usually monolayer.
