GCSE Chemistry Question Analysis Topic: Chemistry - Adsorption
Define adsorption with an example. What is the role of adsorption in heterogeneous catalysts?
Answer:
For GCSE Chemistry, you should know:
Adsorption is the process of a substance's molecules being drawn to and held on the surface of a liquid or a solid, increasing the concentration of those molecules there, e.g. charcoal gas masks.
Adsorption is a crucial stage in heterogeneous catalysis, and it plays a key role in the process. It is the process by which an adsorbate (a gas or solution phase molecule) attaches to the surface atoms of a solid or liquid (the adsorbent).
Work hard for your GCSE Chemistry examination!
End of analysis. Great!
