Chapter 17, Problem 17.52QE

(a)

Interpretation Introduction

Interpretation:

The entropy change for the process of $\text{2}\text{.0 mol}{\text{NH}}_{\text{3}}\left(l\right)$ vaporizes at $-\text{33}{\text{.0}}^{\text{o}}\text{C}$ has to be calculated.

(b)

Interpretation Introduction

Interpretation:

The entropy change for the process of $\text{1}\text{.0 mol}{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}\left(\text{s}\right)$ melts at $-{114}^{\text{o}}\text{C}$ has to be calculated.
