Question

Which of the following adsorptions forms multimolecular layer?

• A. Physical adsorption
• B. Chemical adsorption
• C. Both (A) and (B)
• D. None of these

Hint:

Multilayer adsorption is typically associated with physical adsorption, while chemical adsorption tends to form a single monolayer.

Answer 1

The Correct Option is C

Step 1: Understanding physical and chemical adsorption.
- Physical adsorption occurs due to weak van der Waals forces and can form multilayer adsorption. - Chemical adsorption involves chemical bonds and generally forms a monolayer.
Step 2: Both physical and chemical adsorption.
- Physical adsorption can form a multilayer structure, while chemical adsorption forms a monolayer. - The combination of both processes in certain conditions can lead to a multilayer structure.
Final Answer: \[ \boxed{\text{Both (A) and (B)}} \]
