Freundlich adsorption isotherms for the physical adsorption of a gas at temperature T₁, T₂ and T₃ are shown in the graph given below. The correct relationship between T₁, T₂ and T₃ is
Options
- AT₁ < T₂ < T₃
- BT₃ < T₁ < T₂
- CT₃ < T₂ < T₁
- DT₂ < T₁ < T₃
Correct answer
C. T₃ < T₂ < T₁
Step-by-step solution
Lower the temperature more the adsorption. So, as the temperature increases adsorption decreases. According to Freundlich adsorption isotherm. x m =k p^ 1 / n (n>1) where, x is the mass of gas adsorbed. aligned & or x m = k+ 1 n p & T₃ < T₂ < T₁ aligned
