Shown 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:

Step-by-step solution

' x ' is mass of gas adsorbed on mass ' m ' of the adsorbent at pressure ' p '. The curves in the given adsorption isotherm indicates that at a fixed pressure, there is decrease in physical adsorption with increase in temperature and vice versa. So, the correct order of temperature is : T ₃> T ₂> T ₁
