At `35^@C` , the vapour pressure of `CS_2` is 512 mm Hg and that of acetone is 344 mm Hg . A solution of `CS_2` in acetone has a total vopour pressure of 600 mm Hg. The false statement amongst the following is

Options

A. A mixture of 100 ml of acetone and 100 ml of `CS_2` has a total volume of 200 ml.
B. When acetone and `CS_2` are mixed at `35^@C` , heat must be absorbed in order to produce a solution at `35^@C`
C. When acetone and `CS_2` are mixed at `35^@C` , heat is released .
D. Raoult's law is obeyed by both , `CS_2` and acetone for the solution in which the moles fraction of `CS_2` is 0.25

Answer

B
