Chemistry · Some Basic Concepts of Chemistry
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): One mole of any gas always occupies \( 22.4\text{ L} \) volume at all temperatures and pressures. Reason (R): Volume of a gas depends inversely on pressure and directly on temperature. In the light of the above statements, choose the correct answer from the options given below:
Correct answer · Option A
(A) is false but (R) is true.
Explanation
\( 22.4\text{ L} \) is valid specifically at STP (0°C, 1 bar or 1 atm), not at *all* temperatures and pressures. Thus Assertion is false, Reason is true.
