Chapter 5, Problem 5D.3AE

(i)

Interpretation Introduction

Interpretation: The cooling curve for the given system against $x\left({\text{CF}}_{\text{4}}\right)=0.10$ has to be drawn.

Concept introduction: The azeotropic mixture is defined as a mixture of two or more liquids which evaporates without altering the composition of the mixture.  The azeotropic mixture has a constant boiling point because of the same composition in liquid as well as vapor phase.  The components of azeotropic mixture are not separated by distillation processes.

The cooling curve is a graphical representation of change of phase of compound.  It is plotted between temperature and time.
