Chapter 18, Problem 18.16QP

Interpretation Introduction

Interpretation: The signs of $\Delta S_{\text{sys}}$, $\Delta S_{\text{surr}}$ and $\Delta S_{\text{univ}}$ for the complete combustion of propane in which products include water vapor and carbon dioxide are to be stated.

Concept introduction: Entropy is a thermodynamic property which shows the randomness or disorder of the atoms within the system.

$\Delta S_{\text{sys}}$ is known as the entropy change for a system and $\Delta S_{\text{univ}}$ is entropy change in the universe.

$\Delta S_{\text{surr}}$ is known as entropy change for a surrounding.

To determine: The signs of $\Delta S_{\text{sys}}$, $\Delta S_{\text{surr}}$ and $\Delta S_{\text{univ}}$ for the complete combustion of propane in which products include water vapor and carbon dioxide.
