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

    A)  the rate of dissociation of adsorbed molecules from the surface does not depend on the surface covered

    B)  the adsorption at a single site on the surface may involve multiple molecules at the same time

    C)  the mass of gas striking a given area of surface is proportional to the pressure of the gas

    D)  the mass of gas striking a given area of surface is independent of the pressure of the gas

    Correct Answer: C

    Solution :

    The adsorption of a gas is directly proportional to the pressure of the gas.
