Chapter 6, Problem 20E

Interpretation Introduction

Interpretation: Homogeneous equilibria and manner they differ from heterogeneous equilibrium in terms of $K$ should be explained.

Concept introduction:For the equilibrium as indicated below.

  $a\text{A}+b\text{B}\rightleftharpoons c\text{C}+d\text{D}$

Law of mass action states that for such equilibrium that involves solutions and gases expression of an equilibrium constant in principle is written in accordance with the law of massaction as follows:

  $K=\frac{{\left[\text{C}\right]}^c{\left[\text{D}\right]}^d}{{\left[\text{A}\right]}^a{\left[\text{B}\right]}^b}$

Where,

• $\left[\text{C}\right]$ denotes equilibrium concentration of C.
• $\left[\text{D}\right]$ denotes equilibrium concentration of D.
• $\left[\text{A}\right]$ denotes equilibrium concentration of A.
• $\left[\text{B}\right]$ denotes equilibrium concentration of B.
• $K$ denotes equilibrium constant.
• $a$ , $b$ , $c$ and $d$ are stoichiometric coefficients.
