Which of the following statement about the
composition of the vapour over an ideal a 1 : 1 molar
mixture of benzene and toluene is correct? Assume
that the temperature is constant at 25°C.
(Given : Vapour Pressure Data at 25°C,
benzene = 12.8 kPa, Toluene = 3.85 kPa)
(1) The vapour will contain a higher percentage of
benzene
(2) The vapour will contain a higher percentage of
toluene
(3) The vapour will contain equal amounts of
benezene and toluene
(4) Not enough information is given to make a
predication
