Show below are adsorption isotherms for a gas ‘X’ at temperatures $T_{1}, T_{2} and T_{3}$ :

p and x/m represent pressure and extent of adsorption, respectively. The correct order of temperatures for the given adsorption is :

A
$T_{1} > T_{2} > T_{3}$
B
$T_{3} > T_{2} > T_{1}$
C
$T_{1} = T_{2} = T_{3}$
D
$T_{1} = T_{2} > T_{3}$

Solution:

Adsorption is exothermic process. According to lechatlier's principal exothermic process are favourable for low temperature.

With increase in temperature x/m decreases. so, correct order of
temperature is $T_{3} > T_{2} > T_{1}$
