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

    A)  intermolecular repulsion

    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,\[b=\]volume correction, which arises due to finite size of molecules.
