Surface Chemistry Class 12 Notes – Chapter 5
The event of attracting and keeping the molecule of a substance on the surface of a solid is called adsorption. This results in an increased concentration on the surface than in the bulk. The expanse of adsorption of a gas on a solid material depends on the following factors: surface area of the solid, temperature of the gas, nature of the gas, the pressure of the gas, and nature of solid.
