Chapter 17, Problem 17.8VP

(a)

Interpretation Introduction

Interpretation: The questions based on the Figure are to be answered.

Concept introduction: Entropy is a thermodynamic property which shows the randomness or disorder of the atoms within the system.

In polymerization, the polymer formed by the monomer units has three dimensional structures which are rigid in nature. Due to rigidity there is a restriction in the movement of the molecules and they cannot move freely in the rigid structure.

To determine: The sign of $\Delta S$ for the substance in the given figure.

(b)

Interpretation Introduction

To determine: The sign of $\Delta S$ for the formation of slime in the given figure which is a cross linked polymer of polyvinyl alcohol and borax.

(c)

Interpretation Introduction

To determine: The sign of $\Delta S$ for the sublimation of dry ice in the given figure; the conditions in which this process not be spontaneous

(d)

Interpretation Introduction

To determine: If entropy increases, decreases or remains unchanged when the particulate substances in $\left[\text{A}\right]$ and $\left[\text{C}\right]$ are mixed to create substance in $\left[\text{E}\right]$ depicted in Figure 1 and the affect on the entropy If the particulate substances in $\left[\text{G}\right]$ and $\left[\text{I}\right]$ are mixed to create substance in $\left[\text{E}\right]$ depicted in Figure 1.

(e)

Interpretation Introduction

To determine: If the stated process is spontaneous and if the entropy increases or decreases.

(f)

Interpretation Introduction

To determine: If mixing of all the substances lead to an increase in entropy.
