1.	Which of the 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 coinstant at `25^(@)C`. (Give, vapour pressure data at `25^(@)C`, benzene = 21.8 kPa, toluene = 3.85 kPa)A. The vapour phase will contain equal amounts of benzene and tollutene.B. Not enough information is given to make a predication.C. The vapour phase will contain a higher precentage of benzeene.D. The vapour phase will contain a higher percentage of toluene.
Answer» Correct Answer - c `P_("Benzene")=X_("Benzene")xxP_("Benzene")^(@)` =`1//2xx121.8 k Pa` `P_("tonene")=X_("toluene")xxP_("toluene")^(@)` =`1//2xx3.85=1.925kPa` Since `P_("Benzene")` is more than that of toluene the vapour phses will ciontain higher percentage of benzene
