    In case of CO and \[C{{H}_{4}}\] curve goes to minima then increases with increase in pressure but in case of \[{{H}_{\text{2}}}\] and He the curve is linear because:

    A) Intermolecular interactions tor \[{{H}_{2}}\] and He are very low.

    B) Molecular size or atomic size for \[{{H}_{2}}\] and He is small.

    C) Both [a] and [b]

    D) Neither [a] nor [b]

    Correct Answer: C

    Solution :

    [c] Due to small size of these species (\[{{H}_{2}}\]and He) intermolecular interactions (van der Waal forces) are very low, therefore it is difficult to compress these.
