    A 3 : 2 molar mixture of \[{{N}_{2}}\] and CO is present in a vessel at 500 bar pressure. Due to hole in the vessel, the gas mixture leaks out. The composition of mixture effusing out initially is

    A) \[{}^{n}{{N}_{2}}:{}^{n}CO::1:2\]   

    B) \[{}^{n}{{N}_{2}}:{}^{n}CO::6:1\]

    C) \[{}^{n}CO:{}^{n}{{N}_{2}}::1:2\]   

    D) \[{}^{n}CO:{}^{n}{{N}_{2}}::2:3\]

    Correct Answer: D

    Solution :

    [d] Molar ratio of \[{{N}_{2}}\] and CO is 3:2, i.e., 300 bar and 200 bar, respectively. \[\frac{^{n}{{N}_{2}}}{^{n}CO}=\sqrt{\frac{^{m}CO}{m{{N}_{2}}}}\times \frac{^{P}{{N}_{2}}}{{{P}_{CO}}}\] \[=\frac{300}{200}=\frac{3}{2}\]
