Chapter 17, Problem 17.43QP

Interpretation Introduction

Interpretation: The free energy change for the dissolution in water of $1$ mole of $\text{NaBr}$ and $1$ mole of $\text{NaI}$ at $298\text{K}$ from the given values is to be calculated.

Concept introduction: The free energy change for the dissolution in water is calculated by the formula,

$\Delta G_{\text{soln}}^{\text{ο}}=\Delta H_{\text{soln}}^{\text{ο}}-T\Delta S_{\text{soln}}^{\text{ο}}$

To determine: The free energy change for the dissolution in water of $1$ mole of $\text{NaBr}$ and $1$ mole of $\text{NaI}$ at $298\text{K}$ from the given values.
