💡 Solution & Explanation

Statement I is false because the vapour is richer in the more volatile component *relative to its proportion in the liquid phase*, but not necessarily richer in absolute terms (for instance, if the liquid is 99% less volatile component). Also, for azeotropic mixtures, the vapour and liquid compositions are exactly the same. Statement II is true, as higher volatility corresponds to a lower boiling temperature. Therefore, correct answer is D.
