The Freundlich adsorption isotherm varies with temperature according to the figure given below. Choose the correct option accordingly.
  1. $T_1=303 \mathrm{~K}, T_2=298 \mathrm{~K}, T_3=244 \mathrm{~K}, T_4=195 \mathrm{~K}$
  2. $T_1=303 \mathrm{~K}, T_2=195 \mathrm{~K}, T_3=244 \mathrm{~K}, T_4=298 \mathrm{~K}$
  3. $T_1=195 \mathrm{~K}, T_2=244 \mathrm{~K}, T_3=298 \mathrm{~K}, T_4=303 \mathrm{~K}$
  4. $T_1=195 \mathrm{~K}, T_2=303 \mathrm{~K}, T_3=244 \mathrm{~K}, T_4=298 \mathrm{~K}$

Solution

Freundlich adsorption isotherm, an adsorption isotherm is a graph that represents the variation in the amount of adsorbate $(x)$ adsorbed on the surface of the adsorbent with the change in pressure at a constant temperature. As the temperature increases, adsorption decreases. Therefore, the correct relation is given in option (3).
