Question: Which is the correct order of adsorption strength from highest to lowest?

Options:

Correct Answer: Chemisorption > Physisorption

Solution:

Chemisorption is stronger than physisorption due to the formation of chemical bonds.

Which is the correct order of adsorption strength from highest to lowest?

Which is the correct order of adsorption strength from highest to lowest?

Step 1: Understand what adsorption means. Adsorption is when molecules stick to a surface.
Step 2: Learn about the two types of adsorption: chemisorption and physisorption.
Step 3: Know that chemisorption involves the formation of strong chemical bonds between the adsorbate and the surface.
Step 4: Recognize that physisorption involves weaker forces, like van der Waals forces, which do not create strong bonds.
Step 5: Conclude that since chemisorption involves stronger bonds, it is stronger than physisorption.
