Chapter 15, Problem 108E

Interpretation Introduction

Interpretation: The figure representing equilibrium constant of the halogenation reaction of ethene for the given three different halogens is to be examined. The equilibrium constant of three reactions for three different halogens are to be ranked in the descending order.

Concept Introduction: The equilibrium constant is the ratio of concentrations of products to those of reactants each raised to the power of stoichiometric coefficients. Consider the general chemical reaction as follows:$a\text{A}+b\text{B}\rightleftharpoons c\text{C}+d\text{D}$.

The equilibrium expression for the above reaction is written as follows:

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

Here, the reactants are $\text{A}$ and $\text{B}$, the products are $\text{C and D}$, and the stoichiometric coefficients are $a,b,c,\text{ and }d$.
