Questions & Step-by-Step Solutions
Which of the following is an example of a physical adsorption?
Correct Answer: The adsorption of O2 on activated charcoal
Step 1: Understand what adsorption means. Adsorption is when molecules stick to a surface.
Step 2: Learn the difference between physical adsorption and chemical adsorption. Physical adsorption involves weak forces, while chemical adsorption involves stronger chemical bonds.
Step 3: Identify examples of physical adsorption. Look for cases where molecules attach to surfaces without forming strong bonds.
Step 4: Consider the example given: the adsorption of O2 on activated charcoal. This is a case where oxygen molecules stick to the surface of charcoal using weak forces.
Step 5: Conclude that the adsorption of O2 on activated charcoal is indeed an example of physical adsorption.
