Chapter 3, Problem 11PP

Interpretation Introduction

Interpretation:

Whether the entropy changes for each of the given reaction are positive, negative, or approximately zero is to be stated.

Concept introduction:

Entropy is a measure of the degree of randomness. The more the randomness, the more is the entropy of the system.

Entropy change is relatively small for the reactions where the number of molecules of the products is equal to the number of molecules of the reactants.

Entropy change is positive for a system when it transits from a high randomness (disorder) system to a lower randomness (less ordered) system.
