Chapter 7, Problem 77P

Interpretation Introduction

Interpretation:

The value of reverse reaction rate constant $k^{\text{'}}$ should be determined for given equation.

Concept Introduction:

Chemical reaction reaches to such a level where no change occurs in the concentration of reactants and products which is called as dynamic equilibrium.The equilibrium constant is basically the ratio of total reactants and total products when the reaction reaches to its equilibrium.

The rate of reaction is determined as change of reactants or products per unit time and rate constant is multiplication of concentration of reactants and initial rates of reactions.

For a general equilibrium reaction as follows:

The expression for equilibrium constant of the recation can be written as follows:

$K_{\text{e}q}=\frac{{\left[\text{C}\right]}^{\text{C}}{\left[D\right]}^d}{{\left[\text{a}\right]}^{\text{a}}{\left[B\right]}^b}$

Here, $\left[\text{a}\right]$, $\left[B\right]$, $\left[\text{C}\right]$ and $\left[D\right]$ is concentration of reactant A, B, C and D respectively.
