Which of the following statements about the composition of the vapour over an ideal 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)

Options

A. The vapour will contain a higher percentage of toluene.
B. The vapour will contain equal amounts of benzene and toluene.
C. Not enough information is given to make a prediction.
D. The vapour will contain a higher percentage of benzene.

Answer

D

Explanation

In composition of Benzene of vapour pressure is more hence its proportion of percerntage is more in mixture.
