Chapter 6, Problem 6.20NP

Interpretation Introduction

Interpretation:

The $\Delta G$ for the isothermal expansion should be stated.

Concept Introduction:

The Gibb’s free energy at standard conditions is given by the formula as shown below:

  $\Delta G=-nRT\ln \frac{P_f}{P_i}$

Where,

• $\Delta G°$ is the standard change in Gibb’s free energy.
• $R$ is the Gas constant, 8.314 kJ/mol.
• $T$ is the temperature.
• $P_f$ is final pressure.
• $P_i$ is initial pressure.
• $n$ is the number of mole.
