Chapter 9, Problem 9.129SP

Interpretation Introduction

Interpretation:

The change in value of $\text{ΔS}$, $\text{ΔH}$ and $\text{ΔG}$ for the diffusion process when a bottle of perfumed is opened needs to be explained.

Concept introduction:

The particles of a system remain in motion continuously. The randomness in a system is denoted by entropy of system. As the disorder increases in a system, the entropy of system also increases. The entropy of a system can be calculated with the help of the difference of the entropy the product and reactant.

$\text{ΔrS°= }\Sigma \text{ΔrS°product - }\sum \text{ΔrS°reactant}$

For any reaction the $\text{ΔH}$ can be calculated with the help of following relation:

$\text{ΔrH°= ΣΔrH°product - }\sum \text{ΔrH°reactant}$
