    Identify the gas which is readily adsorbed by activated charcoal:

    A)  \[{{N}_{2}}\]                    

    B)  \[S{{O}_{2}}\]

    C)  \[{{H}_{2}}\]                     

    D)  \[{{O}_{2}}\]

    Correct Answer: B

    Solution :

    Easily liquifiable gases (like \[S{{O}_{2}},N{{H}_{3}},C{{O}_{2}}\] etc.) are adsorbed upto greater extent than the gases like \[{{O}_{2}},{{H}_{2}}{{N}_{2}}\], He etc. which liquify  with great difficulty.
