Question

The vapour pressure of a solution of two liquids, A ($P^\circ = 80$ mm, $X = 0.4$) and B ($P^\circ = 120$ mm, $X = 0.6$) is found to be 100 mm. It shows that the solution exhibits

Prashant Kotian · Accepted Answer

Correct answer: A. Ideal pressure mm. The observed pressure is 100 mm, which is lower than the ideal pressure, indicating a negative deviation. Therefore, correct answer is A.
