NEET 2022 Phase 2 Chemistry - Surface Chemistry Question 4 English

p and $${x \over m}$$ represent pressure and extent of adsorption, respectively. The correct order of temperatures for the given adsorption is :

$${T_1} = {T_2} > {T_3}$$

$${T_1} > {T_2} > {T_3}$$

$${T_3} > {T_2} > {T_1}$$

$${T_1} = {T_2} = {T_3}$$
