Read the Assertion and Reason below and choose the correct option. — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Statement I is incorrect. Intermolecular attraction does not vanish at the critical temperature. Instead, the thermal kinetic energy of the molecules becomes so high that it overpowers the attractive forces, preventing liquefaction regardless of pressure. Statement II is correct; at the critical point, the liquid and vapor phases become indistinguishable and have the exact same density. Therefore, correct answer is D.
