Chapter 13, Problem 4KSP

Interpretation Introduction

Interpretation:

The category of the dissolution of ionic solutes is be chosen when this process causes decrease in the entropy and occurs spontaneously.

Concept introduction:

Entropy is defined as the degree of randomness in the system.

An endothermic process is defined as the process in which the energy of the system increases.

Endothermic process is the process that requires or absorbs heat from the surroundings.

In an endothermic process, potential energy of the system increases resulting in increase in entropy of the system.

An exothermic process is the process where the system releases energy.

In an exothermic process, potential energy of the system decreases resulting in decrease in entropy of the system.
