JEE Main Chemistry question

Not in JEE Main or NEET syllabus

The Langmuir adsorption isotherm is deduced using the assumption:

(A)The adsorption sites are equivalent in their ability to adsorb the particlesCorrect
(B)The heat of adsorption varies with coverage
(C)The adsorbed molecules interact with each other
(D)The adsorption takes place in multilayers

Answer: (A)

Solution

Langmuir's model assumes a uniform surface of equivalent adsorption sites, each capable of holding exactly one adsorbate molecule, with no interaction
