The following fig
• The arrangement of given temperatures in the correct increasing order is -
T1 <T2 <T3.
This is actually the Freundlich adsorption isotherm, which is based upon the relationship
x/m = k.p1/n (n > 1)
where, x is the amount of (mass) a certain gas which is here N2 adsorbed on mass m of the particular adsorbent which is charcoal in this case at pressure p, while k and n are 2 constants which depends on the nature of the gas and the adsorbent while keeping the temperature constant (isotherm).
• In the given curve mass of the N2 adsorbed per gram of the charcoal is plotted against pressure and as physical adsorption is an exothermic process it occurs spontaneously at low temperatures and decreases with increasing temperature the order T1<T2 <T3 is justified.
