Chapter 4, Problem 4.63E

Interpretation Introduction

Interpretation:

The explanation for the fact that the equation that represents the change in chemical potential of gaseous system does not have $n$ variable that is present in the equation that represents change in Gibbs energy of the gaseous system is to be stated.

Concept introduction:

The Gibbs free energy of the system represents the maximum amount of non-expansion work achieved by a thermodynamic system at isothermal and isobaric conditions. The change in Gibbs free energy is used to predict the spontaneity of the process. The change in Gibbs energy of the gaseous system is represented as shown below.

$\Delta G=nRT\ln \frac{p_{\text{f}}}{p_{\text{i}}}$
