    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 volume

    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.
