MHT CET 2023 Chemistry question

Not in JEE Main or NEET syllabus

Which from following phenomena is inversely proportional with adsorption?

(A)Critical temperature of gas
(B)Surface area of adsorbent
(C)Temperature of processCorrect
(D)Pressure of gas

Answer: (C)

Solution

Physical adsorption is exothermic (), so by Le Chatelier's principle it is favoured at low temperature and the extent of adsorption falls as the temperature of the process rises, i.e. adsorption is inversely related to temperature. (a) A gas with a higher critical temperature is more easily liquefied, has
