JEE Main 2021 — Surface Chemistry Question with Solution
From: JEE Main 2021 (Online) 31st August Morning Shift
Question
Select the graph that correctly describes the adsorption isotherms at two temperatures T1, and T2 (T1 > T2) for a gas :
(x - mass of the gas absorbed ; m - mass of adsorbent ; P - pressure)
(x - mass of the gas absorbed ; m - mass of adsorbent ; P - pressure)
Choose an option
Show full solutionCorrect option: A
Correct answer
A

Step-by-step explanation
According to Freundlich adsorption isotherm, in the median range of pressure
= kP
On increasing temperature decreases.
Adsorption is generally exothermic in nature. Hence, correct option is (A).
= kP
On increasing temperature decreases.
Adsorption is generally exothermic in nature. Hence, correct option is (A).
