Chapter 23, Problem 23.118P

(a)

Interpretation Introduction

Interpretation:

The changes of the product and reactant particle has to be predicted.

Concept introduction:

Change in entropy of a system is determined by its initial and final states. In the idealization that a process is reversible, the entropy does not change, while irreversible processes always increase the total entropy.

(b)

Interpretation Introduction

Interpretation:

The ethylenediamine complex is more stable with respect to ligand exchange with water has to be explained.

Concept introduction:

Change in entropy of a system is determined by its initial and final states. In the idealization that a process is reversible, the entropy does not change, while irreversible processes always increase the total entropy.

Geometry of coordination compounds: The study of geometry of the coordination compound helps in understanding the physical and chemical property of the compound.

Stereoisomer: The same molecular formula but different with the arrangements of atoms around the metal ion.  The Ligands are arranged differently in coordination compounds.
