Mass Transfer - Engineering
Q1: A liquid mixture contains 30% o-xylene, 60% p-xylene and 10%. m-xylene (all percentages in w/w). Which of the following statements would be true in respect of this mixture?A The mixture exhibits an azeotrope at 101.3 kPa.
B The composition of the mixture, in percent by volume is: o-xylene 30, p-xylene 60. and m-xylene 10.
C The composition of the mixture in mole percent is: o-xylene 30, p-xylene 60 and m-xyoene 10.
D The mixture contain optical isomers.
ANS:A - The mixture exhibits an azeotrope at 101.3 kPa. The mixture exhibits an azeotrope at 101.3 kPa: An azeotrope is a mixture of two or more components in such proportions that its composition cannot be altered by simple distillation. In this case, the mixture does not exhibit an azeotrope at 101.3 kPa because azeotropes typically occur at specific compositions and conditions where the vapor and liquid phases have the same composition. The given mixture consists of three different isomers of xylene (o-xylene, p-xylene, and m-xylene) in different proportions, which does not meet the criteria for forming an azeotrope.
