The Langmuir adsorption isotherm is deduced by using the assumption :
Updated On: Jul 9, 2024
- the adsorption takes place in multilayers
- the adsorption sites are equivalent in their ability to adsorb the particles
- the heat of adsorption varies with coverage
- the adsorbed molecules interact with each other
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The main points of Langmuir- theory of adsorption are as
(i) Adsorption takes place on the surface of the solid only till the whole of the surface is completely covered with a unimolecular layer of the adsorbed gas.
(ii) Adsorption consist of two opposing processes
(a) condensation and (b) evaporation condensation.

Concepts Used:
Adsorption
Heinrich Kayser, the German physicist was the first to coin the term adsorption. Adsorption can be explained as a surface phenomenon where particles remain attached on the top of a material. Generally, it comprises the molecules, atoms, liquid, solid in a dissolved stage, even the ions of a gas that are attached to the surface. Much to our surprise, the consequence of surface energy i.e. adsorption is present in biological, physical, chemical, and natural systems and are used in many industrial applications.
