Chapter 12, Problem 5RQ

Interpretation Introduction

Interpretation: The terms ‘homogeneous equilibria’ and ‘hetergeneous equilibria’ constant’ are to be defined. The difference in writing the $K$ expressions for homogeneous versus the heterogeneous reactions has to be stated. The species included in the $K$ expression and the ones that are not included are to be stated.

Concept introduction: The equilibria can be termed as a homogeneous equilibria or a heterogeneous equilibria based on the number of phases existing in a given chemical reaction.

To determine: A definition for the terms ‘homogeneous equilibria’ and ‘hetergeneous equilibria; the difference in writing the $K$ expressions for homogeneous versus the heterogeneous reactions; the species included and excluded from the $K$ expression.
