Chapter 6, Problem 49P

Interpretation Introduction

Interpretation:

Appropriate representation relevant to given equilibrium constants should be assigned.

Concept introduction:

For a reversible reaction, equilibrium constant ( $K_{eq}$ ) is defined as follows,

  $\begin{array}{l}aA+bB\rightleftarrows cC+dD\\ \text{equilibrium constant = }{K}_{eq}=\frac{{\left[C\right]}^c\times {\left[D\right]}^d}{{\left[A\right]}^a\times {\left[B\right]}^b}\end{array}$

The magnitude of $K_{eq}$ reveals information about the composition of the reaction mixture at equilibrium,

  $\begin{array}{l}\text{When }{K}_{eq}=1,\text{ both the reactants and products are present at equilibrium}\\ \text{When }{K}_{eq}\text{> 1, equilibrium favors the products}\\ \text{When }{K}_{eq}\text{< 1, equilibrium favors the reactants}\end{array}$
