Chapter 18, Problem 18.21QP

(a)

Interpretation Introduction

Interpretation: The component in each of the given pairs that has greater entropy is to be identified.

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

The entropy is maximum in the gas phase and minimum in the solid phase

To determine: The component of the pair of $1$ mole of ${\text{S}}_2\left(g\right)$ and $1$ mole of ${\text{S}}_8\left(g\right)$ that has a greater entropy.

(b)

Interpretation Introduction

To determine: The component of the pair of $1$ mole of ${\text{S}}_2\left(g\right)$ and $1$ mole of ${\text{S}}_8\left(s\right)$ that has the greater entropy.

(c)

Interpretation Introduction

To determine: The component of the pair of $1$ mole of ${\text{O}}_2\left(g\right)$ and $1$ mole of ${\text{O}}_3\left(g\right)$ that has the greater entropy.

(d)

Interpretation Introduction

To determine: The component og the pair of $1$ gram of ${\text{O}}_2\left(g\right)$ and $1$ gram of ${\text{O}}_3\left(g\right)$ that has the greater entropy.
