Effect of temperature and pressure on the adsorption of gases on solids-

Temperature- According to Le-Chatelier’s principle the physical adsorption readily occurs at low temperature and adsorption rate is slow at high temperature.

Pressure-  As we increase the pressure the amount of gas adsorbed on adsorbent is increased as the volume of gas decreases. Since it is an exothermic process, the physical adsorption occurs fast at low temperature and decrease with increase in pressure.
