    In van der Waals equation of state of the gas law, the constant b is a measure of

    A)   intermolecular repulsions

    B)  intermolecular attraction

    C)  volume occupied by the molecules

    D)  intermolecular collisions per unit volum

    Correct Answer: C

    Solution :

     van der Waals equation for one mole of a gas is \[\left[ p+\frac{a}{{{V}^{2}}} \right][V-b]=RT\] where, b is volume correction. It arises due to effective size of molecules.
