Question

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.

Answer 1

Correct option (a) the adsorption sites are equivalent in their ability to adsorb the particles

Explanation :

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