Chapter 4, Problem 4.123P

Interpretation Introduction

Interpretation:

The necessary condition to reach equilibrium in case of decomposition reaction that leads to gaseous product is to be determined.

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:

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

Decomposition redox reactions are the reactions in which one compound decomposed to form one or more product. The reaction has at least one of the product in element form. Decomposition redox reactions can be further classified as thermal decomposition and electrolytic decomposition. In thermal decomposition, heat is employed for the decomposition reaction while in electrolytic decomposition electrical energy is employed for the decomposition reaction. The general representation of decomposition redox reaction is:

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