The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided. ### Step 1: Analyze the Assertion (A) Assertion (A) states: "1 mol of H₂ and N₂ have the same volume at the same temperature and pressure." - According to the Ideal Gas Law, \( PV = nRT \), where: - \( P \) = pressure - \( V \) = volume - \( n \) = number of moles - \( R \) = ideal gas constant - \( T \) = temperature - If we have 1 mole of any gas (including H₂ and N₂) at the same temperature and pressure, the volume occupied by the gas will be the same. This is a fundamental principle of gases. **Conclusion for Assertion (A)**: The assertion is correct. ### Step 2: Analyze the Reason (R) Reason (R) states: "1 mol gas at STP occupies 24.4 L volume." - Standard Temperature and Pressure (STP) is defined as 0°C (273.15 K) and 1 atm pressure. - At STP, one mole of an ideal gas occupies approximately 22.4 L, not 24.4 L. **Conclusion for Reason (R)**: The reason is incorrect. ### Final Conclusion - Assertion (A) is correct. - Reason (R) is incorrect. Thus, the correct answer is that Assertion (A) is true, and Reason (R) is false.
