    Gases X, Y, Z, P and Q have the van der Waals constants a and b (in CGS units) as shown below:
    X Y Z P Q
    a 6 6 20 0.05 30
    b 0.025 0.15 0.1 0.02 0.2
    The gas with the highest critical temperature is:

    A) P                            

    B)        Q

    C) Y                             

    D)        Z

    E) X

    Correct Answer: B

    Solution :

    The value of van der Waals constant a increases in the same order as the critical temperature. Here, the value of a is highest for Q hence, gas Q has the highest critical temperature.
