Question

At 35°C, the vapour pressure of CS is 512 mm Hg and that of acetone is 344 mm Hg. A Solution of CS in acetone has a total vapour pressure of 600 mm Hg. The false statement amongst the following is:

(A) CS and acetone are less attracted to each other than to themselves.
(B) A mixture of 100 ml CS and 100 ml acetone has a volume < 200 ml.
(C) Heat must be absorbed to produce the Solution at 35°C

Correct answer: B. ution of CS in acetone has a total vapour pressure of 600 mm Hg. The false statement amongst the following is: (1) CS and acetone are less attracted to each other than to themselves. (2) A mixture of 100 ml CS and 100 ml acetone has a volume < 200 ml. (3) Heat must be absorbed to produce the Solution at 35°C (4) Raoult's law is not obeyed by this system. + 2 2 i t (g) (g) (g) k = × log 2.303 t Pi (2Pi −Pt) k = × log 2.303 t (2Pi −Pt) Pi k = × 2.303 t Pi (2Pi −Pt) k = × log 2.303 t 2Pi (2Pi −Pt) 12 –1 –26000K/T –1 –1 –1 + 2+ 2+ + 2 2 2 2 LEADER COURSE_PHASE - 1 9610ZMD800101250003
