A solution is made by mixing one mole of volatile liquid A with 3 moles of volatile liquid B. The vapour pressure of pure A is 200 mm Hg and that of the solution is 500 mm Hg. The vapour pressure of pure B and the least volatile component of the solution, respectively, are

1. 600 mm Hg, B
2. 600 mm Hg, A
3. 1400 mm Hg, A
4. 1400 mm Hg, B CAREER POINT CAREER POINT Ltd., CP Tower, IPIA, Road No.1, Kota (Raj.), Ph: 081-47250011 www.careerpoint.ac.in 15 JEE Main Online Paper
