Where have you got it from? Explain your question.

As we know the physisorption is an exothermic process since the translation degree of adsorption reduces with increase of temperature (dS = -ve), so for the case of immobile type chemisorption. But the things happen differently for dissociative chemisorption, where the translation degree of adsorption increases with the increase of temperature. 

Thanks for your response. I am talking about the adsorption of gas over the solid surface.

Thanks a lot for your answer and the link you've provided. I am looking into this, and thanks once again for your advance assistance.

Dear Prantic and Hossein, thank you for your discussion. So the situation has been clarified and admits a good answer. If we think about a good kinetic model - then gas is easily described by a boltsmann like equation, and sorption is boundary condition for it.  But I cant imagion a model rhat differs those two different processes.( for dissociative chemisorption, where the translation degree of adsorption increases with the and for dissociative chemisorption, where the translation degree of adsorption increases with the). There are several welknoun boundary conditions - maxwell conditions. So the principle answer is clear - because of the difference of those maxwell conditions. But torealise what condition correspond to what case of your answer - either< Hossein, explain more thourely the difference: the increse of temperature willbe a siple consequanse of molecular model. Or, Prantic, show us other pages of this article, rather than first.
