Question

The adsorption of hydrogen on charcoal is which type of absorption?

Answer 1

Adsorption:

1. The process of one substance creating a film or coating on the surface of another is known as adsorption.
2. The substance that is adsorbed is known as the adsorbate, whereas the surface that is adsorbed is known as the adsorbent. Adsorption is brought about by the Van der Waals force between the molecules of the adsorbent and the molecules of the adsorbate.

Occlusion:

1. When some metals adsorb hydrogen on their surfaces, dissociative chemisorption takes place.
2. The process of hydrogen atoms adhering to a surface generates a significant amount of heat.
3. This heat decreases with an increase in the adsorption surface.
4. Gas adsorption on a metal surface is referred to as occlusion.

So-called "occlusion" refers to the process of hydrogen adsorption on a metal surface, and the hydrogen is referred to as "occluded hydrogen."
