Q. The Langmuir adsorption isotherm is deduced using the assumption

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

[Solution from source] Langmuir's model assumes a monolayer on equivalent adsorption sites, with no interaction between adsorbed molecules and a heat of adsorption independent of coverage. The other options contradict these assumptions. Answer (1).
