Stoichiometry - Engineering

Q1:

Boiling point of a non-homogeneous mixture of immiscible liquids is __________ that of any one of its separate components.

A lower than

B higher than

C equal to

D either (a) or (b); depends on the liquids

ANS:A - lower than

The boiling point of a non-homogeneous mixture of immiscible liquids can vary depending on the composition of the mixture and the vapor pressure of its components. In general:

  • If the components have significantly different boiling points, the boiling point of the mixture will typically be between the boiling points of its separate components.
  • If one component has a much lower boiling point than the other, it may vaporize preferentially, lowering the boiling point of the mixture.
  • If one component has a much higher boiling point than the other, it may remain largely unvaporized, resulting in a boiling point closer to that of the higher boiling component.
So, the correct answer is: either (a) or (b); depends on the liquids
