Chapter 4, Problem 4.125P

Interpretation Introduction

Interpretation:

The reason for the presence of $\text{NO}$, ${\mathrm{Br}}_{\text{2}}$, and $\text{NOBr}$ in the product mixture when a mixture either a mixture of $\text{NO}$ and ${\mathrm{Br}}_{\text{2}}$ or pure nitrosyl bromide $\left(\text{NOBr}\right)$ is placed in a vessel is to be explained.

Concept introduction:

Equilibrium is that state of a reaction when the rate of forward direction that leads to product side is the same as the rate of backward direction that leads to reactant site. The concentration of the species present in the reaction remains constant at equilibrium. The general representation of a reversible reaction is:

$\text{A}\left(g\right)+\text{B}\left(g\right)\rightleftharpoons \text{C}\left(g\right)+\text{D}\left(g\right)$

Equilibrium is a dynamic process because the concentration of reactants and products remain constant but the forward and backward reaction continues to occur.

Combination redox reactions are the reactions in which two or more reactants combine to form a single product. The reaction has at least one of the reactant in the element form. Combination redox reactions can be classified into two types. First one is when two elements combine to form the product and the second one is when a compound and an element combine to form the product. The general representation of combination redox reaction is:

$\mathrm{X}+\mathrm{Y}\to Z$
