JEE Main & Advanced Chemistry States of Matter / पदार्थ की अवस्थाएँ - गैस एवं द्रव Question Bank Critical state and Liquefaction of gases

  • question_answer
    The Vander Waal's constant 'a' for the gases \[{{O}_{2}},\,{{N}_{2}},\,N{{H}_{3}}\] and \[C{{H}_{4}}\]are 1.3, 1.390, 4.170 and 2.253 \[{{L}^{2}}\,atm\,mo{{l}^{-2}}\] respectively. The gas which can be most easily liquefied is [IIT 1989]

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

    B)                 \[{{N}_{2}}\]

    C)                 \[N{{H}_{3}}\]  

    D)                 \[C{{H}_{4}}\]

    Correct Answer: C

    Solution :

                    Value of constant a is greater than other for \[N{{H}_{3}}\] that?s why \[N{{H}_{3}}\]can be most easily liquefied.
