Chapter EQ, Problem 19PQ

Interpretation Introduction

Interpretation:

When the initial concentration of AB₃ is 0.1 M and the equilibrium concentration of A is x. The expression for the equilibrium constant has to be written.

Concept introduction:

Equilibrium constant :

Equilibrium constant $\left(\text{K}\right)$ is defined as ratio of products to reactants.

Consider following reaction,

    $\text{aA}+\text{bB}\leftrightharpoons \text{cC}+\text{dD}$

The equilibrium constant for the given reaction is shown below,

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

Where,

    $\text{K}$ is the equilibrium constant
