Shown below are adsorption isotherms for a gas 'X' at temperatures $T_1$, $T_2$ and $T_3$:
p and $\frac{x}{m}$ represent pressure and extent of adsorption, respectively. The correct order of temperatures for the given adsorption is:
p and $\frac{x}{m}$ represent pressure and extent of adsorption, respectively. The correct order of temperatures for the given adsorption is:Detailed Solution
Physical adsorption is exothermic, so as the temperature increases the extent of adsorption of a gas on a solid decreases. The lowest curve ($T_3$) is at the highest temperature: $T_3>T_2>T_1$.
