The Langmuir adsorption isotherm is deduced using the assumption a)The adsorbed molecules interact with one another b)The adsorbed occures in multi layers c)The adsorption sites are equivalent in their ability to adsorb the particles d)The beat of adsorption varies with coverage
ANS:C
Whenever a gas is in contact with a solid there will be an equilibrium established between the molecules in the gasphase and the corresponding adsorbed species (molecules or atoms) which are bound to the surface of the solid.So it depends on the adsorption sites.
