Chapter 17, Problem 17.101AP

(a)

Interpretation Introduction

Interpretation: The given oxides of copper are to be named. The temperature range for which the given reaction is spontaneous is to be predicted and the reason for the larger value of standard molar entropy of ${\text{Cu}}_{\text{2}}\text{O}\left(s\right)$ than $\text{CuO}\left(s\right)$ is to be stated.

Concept introduction: Entropy is a thermodynamic property that provides a measure of the randomness of the atoms in the system. The standard molar entropy of a substance is the entropy of one mole of a compound in its standard state.

To determine: The names of the given oxides of copper.

(b)

Interpretation Introduction

To determine: The temperature for which the given reaction is spontaneous.

(c)

Interpretation Introduction

To determine: The reason for the larger value of standard molar entropy of ${\text{Cu}}_{\text{2}}\text{O}\left(s\right)$ than $\text{CuO}\left(s\right)$.
