Chapter 8, Problem 8.19P

Interpretation Introduction

Interpretation:

The free energy of mixing of one mole of isotopically labeled hexane in one liter of ordinary hexane is to be calculated.

Concept introduction:

The Gibbs energy or Gibbs function is a thermodynamic quantity that is used for the representation of thermodynamic state of a system. It is used to evaluate the maximum amount of reversible work performed by a thermodynamic system at constant temperature and pressure. The free energy of mixing is calculated by using the formula,

$\Delta G_{\text{mixing}}=-T\Delta S_{\text{mixing}}$
