JEE MAIN - Chemistry (2022 - 27th July Morning Shift - No. 4)
Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : Activated charcoal adsorbs SO2 more efficiently than CH4.
Reason R : Gases with lower critical temperatures are readily adsorbed by activated charcoal.
In the light of the above statements, choose the correct answer from the options given below.
Both A and R are correct and R is the correct explanation of A.
Both A and R are correct but R is NOT the correct explanation of A.
A is correct but R is not correct.
A is not correct but R is correct.
Explanation
More polar gases easily adsorbs on activated charcoal.
And more polar gases has more (higher) critical temperature as compared to non-polar or less polar gases.
$\therefore$ Gases with higher critical temperature adsorbed more.
And more polar gases has more (higher) critical temperature as compared to non-polar or less polar gases.
$\therefore$ Gases with higher critical temperature adsorbed more.
