Chapter 18, Problem 18.29QP

Interpretation Introduction

Interpretation: Whether precipitation reactions tend to have $\Delta S_{\text{rxn}}^{°}$ values that are greater than zero or less than zero is to be explained.

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

The difference in the entropy of the reactant and products is known as the change in the entropy of a reaction $\Delta S_{\text{rxn}}^{°}$.

To determine: If precipitation reactions tend to have $\Delta S_{\text{rxn}}^{°}$ values that are greater than zero or less than zero.
