Chapter 12, Problem 60QP

Interpretation Introduction

Interpretation:

The units of value substituted in the brackets in equilibrium constant expression is to be determined.

Concept Introduction:

Consider the above equation,

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

The equilibrium expression has reactant concentration in the numerator and product concentration in the denominator (represented by brackets).

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

Here, the products and reactants are raised to the power equals to the stoichiometric coefficients of the reactants and products.

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