Question: What is the primary difference between physisorption and chemisorption? (2023)

Options:

Physisorption is stronger than chemisorption
Chemisorption involves chemical bonds, while physisorption involves van der Waals forces
Physisorption is irreversible, while chemisorption is reversible
Chemisorption occurs at lower temperatures than physisorption

Correct Answer: Chemisorption involves chemical bonds, while physisorption involves van der Waals forces

Exam Year: 2023

Solution:

The primary difference is that chemisorption involves the formation of chemical bonds, while physisorption involves weaker van der Waals forces.

What is the primary difference between physisorption and chemisorption? (2023)

Step 1: Understand that physisorption and chemisorption are two ways that molecules can attach to a surface.
Step 2: Know that physisorption is a weak attachment, like a light hug, using van der Waals forces.
Step 3: Learn that chemisorption is a strong attachment, like a firm handshake, where actual chemical bonds are formed.
Step 4: Remember that the key difference is the strength of the attachment: weak for physisorption and strong for chemisorption.
