$T_3 > T_2 > T_1$

Vedclass · Answer

(B) Physical adsorption is an exothermic process. According to Le Chatelier's principle,an increase in temperature decreases the extent of adsorption $(\frac{x}{m})$ at a constant pressure.From the given graph,at any constant pressure $p$,the extent of adsorption follows the order: $(x/m)_{T_1} > (x/m)_{T_2} > (x/m)_{T_3}$.Since adsorption decreases with an increase in temperature,the corresponding temperatures must follow the inverse order: $T_1  T_2 > T_1$.

Shown below are adsorption isotherms for a gas '$X$' at temperatures $T_1$,$T_2$,and $T_3$. Here,$p$ and $\frac{x}{m}$ represent pressure and the extent of adsorption,respectively. The correct order of temperatures for the given adsorption is:
