Chapter 4, Problem 4.30P
Interpretation Introduction

Interpretation:

A description about the changes observed when a liquid mixture of composition XDEL=0.5 is cooled from 45C has to be done.

Concept Introduction:

A state of matter that is uniform throughout in chemical composition and physical state is known as phase.

Phase diagram is a graphical representation of all the equilibrium phase as a function of temperature, pressure and composition.

The lever rule is mainly used to determine compositions of phases and the relative proportions of phases to each other in Binary diagrams of compounds and using the lever rule we can determine quantitatively the relative composition of a mixture in a two phase region in a phase diagram.

According to lever rule, we can write,

  n=n'+n''

Where,

n': Total amount of molecule in one phase

n'': Total amount in the other phase

The total amount of A in the sample is nxA where xA it is the overall mole fraction of A in the sample. The overall amount of A is also the sum of its amounts in the two phases, where it has the mole fractions xA'andxA'' respectively.

Thus,

  nxA=n'xA'+n''xA''n'(xA'xA)=n''(xAxA'')
