    On the basis of nature of force existing between adsorbate and adsorbent adsorption can be of the following two types 1. Physiosorption 2. Chemisorption. Which of the following is incorrect regarding physisorption?

    A)  Adsorption on solid is reversible

    B)  Adsorption is spontaneous

    C)  Adsorption increases with increase in temperature

    D)  Both AH and AS are negative

    Correct Answer: C

    Solution :
