    During adsorption

    A) \[T\Delta S\] is positive      

    B) \[\Delta H-T\Delta S\] is negative

    C) \[\Delta H\] is positive

    D) \[T\Delta S\] and \[\Delta G\] become zero

    Correct Answer: B

    Solution :

    [b]\[\Delta G=\Delta H-T\Delta S\]. Adsorption is spontaneous process \[\Delta G\]should be negative. Hence \[\Delta H-T\Delta S\] should be negative.
