Chapter 15, Problem 51E

Interpretation Introduction

Interpretation:

The value of equilibrium constant for the given reaction is to be calculated.

${\text{COCl}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons \text{CO}\left(\text{g}\right)+{\text{Cl}}_{\text{2}}\left(\text{g}\right)$

Concept introduction:

The equilibrium constant is the ratio of concentrations of products to thoseof 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 $a,b,c,\text{ and }d$.
