The Langmuir adsorption isotherm is deduced using the assumption.

A

The adsorption takes place in multilayer

B

The adsorption sites are equivalent in their ability to adsorb the particle

C

The heat of adsorption varies with coverage

D

The adsorbed molecules interact with each other

Text Solution

Verified by Experts

The correct Answer is:
B
Every adsorption site is equivalent and the ability of the gas molecule to bind there is independent of whether the neighbouring sites are occupied or not.
