Question

Assertion :A gas with higher critical temperature is adsorbed more than a gas with lower critical temperature. Reason: Higher critical temperature implies that the gas is more easily liquefiable.

• A. If both (A) and (R) are true and (R) is the correct explanation of (A).
• B. If both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. If (A) is correct, but (R) is incorrect.
• D. If (A) and (R) are both incorrect.

Answer 1

The correct option is A If both (A) and (R) are true and (R) is the correct explanation of (A).

A gas with higher critical temperature liquefies easily.So the gas which liquefies easily adsorbs more than a gas which cannot liquefies easily ( lower critical temperature).

So both assertion and reason are correct and reason is the correct explanation for assertion.
Hence option A is correct.
