In the context of adsorption, what does the term 'selectivity' refer to? (2022)

Step 1: Understand what adsorption means. Adsorption is when molecules stick to a surface.
Step 2: Learn about adsorbents. An adsorbent is the material that captures the molecules.
Step 3: Know what selectivity means. Selectivity is about choosing one thing over another.
Step 4: Combine the ideas. In adsorption, selectivity means the adsorbent prefers one type of gas over another.
Step 5: Recognize the importance. This preference is important for separating different gases in various processes.

Selectivity in Adsorption – Selectivity refers to the ability of an adsorbent to preferentially adsorb one type of molecule over another, which is important in processes like gas separation.
