Vedclass · Answer

(C) The Freundlich adsorption isotherm represents the variation in the amount of adsorbate $(x/m)$ adsorbed on the surface of an adsorbent with the change in pressure $(p)$ at a constant temperature.Physical adsorption is an exothermic process. According to Le Chatelier's principle,as the temperature increases,the extent of adsorption decreases.In the given graph,for a constant pressure,the amount of adsorption $(x/m)$ follows the order: $T_1 > T_2 > T_3 > T_4$.Since adsorption decreases with an increase in temperature,the corresponding temperatures must follow the order: $T_1 Comparing the given values,the order $195 \ K Therefore,the correct option is $(C)$.

The Freundlich adsorption isotherm varies with temperature according to the figure given below. Choose the correct option accordingly.
