Question: Which of the following is NOT a method to increase the adsorption capacity of a solid? (2023)

Options:

Correct Answer: Increasing the temperature

Exam Year: 2023

Solution:

Increasing the temperature generally decreases the adsorption capacity for physisorption, as it can overcome the weak van der Waals forces.

Which of the following is NOT a method to increase the adsorption capacity of a solid? (2023)

Which of the following is NOT a method to increase the adsorption capacity of a solid? (2023)

Step 1: Understand what adsorption means. Adsorption is when molecules stick to the surface of a solid.
Step 2: Know that there are methods to increase how much can stick to the solid, called adsorption capacity.
Step 3: Identify common methods to increase adsorption capacity, such as increasing surface area or using different materials.
Step 4: Learn about physisorption, which is a type of adsorption that involves weak forces.
Step 5: Recognize that increasing temperature can make molecules move faster and overcome these weak forces.
Step 6: Conclude that increasing temperature is NOT a method to increase adsorption capacity for physisorption.
