Chapter 8, Problem 8.99SP

Interpretation Introduction

Interpretation:

$\Delta H,\Delta G,\Delta S$ for the process of diffusion of  gaseous molecules has to be described.

Concept Introduction:

• The term free energy G,  refers to energy available in the system to do work.
• $\Delta G$ refers to change in free energy change and it is expressed as,

$\Delta G=\Delta H-T\Delta S$

• Spontaneous process has positive entropy value and negative free energy, enthalpy value.
• Non-spontaneous process tends to proceed with negative entropy value and positive free energy and enthalpy.
