JEE Main 2023 — Surface Chemistry Question with Solution

JEE Main 2023 (12 Apr Shift 1)

Question

Four gases, A, B, C and D have critical temperatures 5.3, 33.2, 126.0 and 154.3K respectively

For their adsorption on a fixed amount of charcoal, the correct order is :

Choose an option

Show full solutionCorrect option: C
Correct answer
CD>C>B>A

Step-by-step explanation

Critical temperature of a gas is the temperature at or above which vapor of the gas cannot be liquefied, no matter how much pressure is applied. The extent of adsorption is directly proportional to the critical temperature of the gas. Higher is the critical temperature of the gas, greater is the extent of adsorption.

Order of Tc    D>C>B>A

Order of adsorption D>C>B>A
