Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Types of adsorption.
Step 1: Physical adsorption involves weak intermolecular forces.
Step 2: These are van der Waals’ forces.
Step 3: Chemical adsorption involves strong covalent/ionic bonds.
Conclusion:
Physical adsorption uses van der Waals’ forces.
