The Langmuir adsorption isotherm is deduced using the assumption.

A

The heat of adsorption varies with coverage

B

The adsorbed molecules interact with each other

C

The adsorption takes place in multilayers.

D

The adsorption sites are equivalent in their ability to adsob the particles.

Text Solution

Verified by Experts

The correct Answer is:
D

Langmuir adsorption isotherm is based on the assumption that every adsorption site is equivalent and that the ability of a particle to bind there is independent of whether or not nearby sites are occupied.
