JEE Main 2006 Chemistry question

Not in JEE Main or NEET syllabus

In Langmuir's model of adsorption of a gas on a solid surface

(1)the rate of dissociation of adsorbed molecules from the surface does not depend on the surface covered
(2)the adsorption at a single site on the surface may involve multiple molecules at the same time
(3)the mass of gas striking a given area of surface is proportional to the pressure of the gasCorrect
(4)the mass of gas striking a given area of surface is independent of the pressure of the gas

Answer: (3)

Solution

In Langmuir's model the rate of adsorption is proportional to the rate at which gas molecules strike the surface, which (from kinetic theory) is proportional to
