Questions & Step-by-Step Solutions

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.
