Show hintHide hint
Consider what happens when particles cling to a surface.
Question 2.
What is an adsorbate?
Show hintHide hint
Think about what is being collected on the surface.
3Question 3.
What is physisorption?
- A. Weak van der Waals forces
- B. Strong chemical bonds
- C. No interaction at the surface
Show hintHide hint
Recall the type of forces that allow for reversible interactions.
4Question 4.
Chemisorption is generally irreversible.
- True
- False
Show hintHide hint

Question 5.
How would the adsorption of a gas on a solid surface be affected if the solid is heated? Provide a detailed explanation for both types of adsorption.
Show hintHide hint
Consider how heat changes interaction dynamics.
Question 6.
A gas is being adsorbed on an activated carbon surface. If the gas is replaced with another gas, what factors must be considered to ensure efficient adsorption?
Show hintHide hint
Think about what features of both the gas and adsorbent will facilitate or hinder absorption.
