Q. At 1200°C, mixture of Cl2 and Cl-atoms (both in gaseous state) effuses 1.16 times as fast as a gas of molar mass 87.6 g mol-1, under identical conditions. What is the percentage dissociation of Cl2 into Cl-atoms ?
    Correct answer is '9'. Can you explain this answer?

    Direction (Q. No.22) This section contains 1questions. when worked out...
    The rate of effusion of a gas is inversely proportional to its molecular weight.
    r∝1/√M
    Let x be the average molecular weight of a mixture of Cl2 and Cl atoms.The molecular weight of krypton is 87.6.
    r(mixture ofCl2 and Cl atoms)/rX =√(MX/M(mixture of Cl2 and Cl atoms))
    Substitute values in the above expression, we get:
    1.16=√(87.6/x)
    or x=65.37
    Also, 65.37 = [(100−y)×71+y×35.5]/100
    or y = 15.8
    So, in 1000 moles species 842 moles is Cl2 molecules and 158 moles is  Cl atom.
    So, initial moles of Cl2
    =842+185/2
    So, % fraction dissociated 
    185/2/(842+185/2)×100=9.89 % = 9%
