Questions & Step-by-Step Solutions
Which of the following is an example of physisorption?
Correct Answer: Oxygen on activated charcoal
Step 1: Understand what physisorption means. It is a type of adsorption where molecules stick to a surface through weak forces called van der Waals forces.
Step 2: Identify examples of physisorption. Look for cases where molecules are held to a surface without forming strong chemical bonds.
Step 3: Consider the example given: oxygen being adsorbed on activated charcoal. This is a classic case of physisorption because the interaction is weak.
Step 4: Confirm that the example fits the definition of physisorption by checking if it involves weak forces rather than strong chemical bonds.
