    Identify the correct statement for the adsorption of a real gas on charcoal at 1 atm and \[\text{15}{{\,}^{\text{o}}}\text{C}\text{.}\]

    A)  gases which are small in molecular size are adsorbed more

    B)  decrease in pressure increases the extent of adsorption

    C)  gases which are easily liquefiable are adsorbed more in quantity

    D)  gas which has a behaviour similar to an inert gas is adsorbed more

    Correct Answer: D

    Solution :

    Gases which have high critical temperature, have strong van der Waals' forces of attraction and hence, area adsorbed to a greater extent.
