    The critical temperature of \[{{O}_{2}},{{N}_{2}},{{H}_{2}}\] and \[C{{O}_{2}}\] are 154.3 K, 126 K, 33.2 K and 304 K. The extent of adsorption on tungsten may be highest in case of

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

    B)  \[{{N}_{2}}\]

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

    D)  \[C{{O}_{2}}\]

    Correct Answer: D

    Solution :

                     Higher the critical temperature, higher is the ease of liquification and easily liquifiable gases are adsorbed more readily. Among the given, \[C{{O}_{2}}\] has the highest critical temperature, thus it will be adsorbed readily.
