As adsorption is a exothermic process so low temperature is favoured in it.Then why in chemical adsorption high temperature is favoured?

dear raman 
in chemical adsorption , you have a strong bond between the adsorbate and adsorbent . 
so, once you increase the temp more the no of molecule will get adsorbed on the surface so, the extent of adsoprtion will increase , and once the surface will full of molecule , then by attaining the maximum limit , the extent of adsorption again decrease by increasing the temp .
