Chapter 3.3, Problem 13E

a)

Interpretation Introduction

Interpretation: Melting points of pure Q and R should be determined.

Concept introduction: Melting point is the temperature that involves the conversion of a substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

b)

Interpretation Introduction

Interpretation: Melting point and composition of eutectic mixture should be determined.

Concept introduction: Melting point is the temperature that involves the conversion of a substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

Eutectic mixture is composed of two or more than two non-interactive components to make new compounds but prevents the crystallization process of each other. This results in the formation of a system with melting points less than each of the two components.

c)

Interpretation Introduction

Interpretation: Whether mixture of 20 mol % Q and 80 mol % R melt if heated to 120 °C , 160 °C or 75 °C should be determined.

Concept introduction: Melting point is the temperature that involves the conversion of a substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

d)

Interpretation Introduction

Interpretation: Prediction about composition of mixture of Q and R if it melts at 105110 °C should be determined.

Concept introduction: Melting point is the temperature that involves the conversion of a substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.
