Chapter 12, Problem 68QP

Interpretation Introduction

Interpretation:

The equilibrium constant for the reverse reaction of the given reaction is to be determined.

Concept Introduction:

Consider the above equation.

$\text{aA}+b\text{B}\to c\text{C}+d\text{D}$

The equilibrium expression has concentrations of the reactants in the numerator and concentrations of the products in the denominator.

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

Here, the products and the reactants are raised to the power equal to the stoichiometric coefficient of the reactants and the products.

In the above expression, the brackets show the molar concentration of reactants and products.
