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 because H₂ and Cl₂ are reacting gases (they react to form HCl), so they do not simply mix without interacting. Dalton's law of partial pressures only applies to non-reacting gas mixtures. Statement II is the correct definition of Dalton's law. Therefore, correct answer is D.
