Chapter 18, Problem 87E

Interpretation Introduction

Interpretation:

The change in the equilibrium on altering the reacting species in reaction, $4{\text{NH}}_3\left(\text{g}\right)+7{\text{O}}_2\left(\text{g}\right)\rightleftharpoons 6{\text{H}}_{\text{2}}\text{O}\left(\text{g}\right)+4{\text{NO}}_2\left(\text{g}\right)+\text{energy}$ is to be stated.

Concept introduction:

Equilibrium reaction is a reaction where, the rate of forward reaction is equal to the backward reaction. According to Le Chatelier’s Principle, if equilibrium is disturbed by changing the conditions like temperature, pressure or concentration, the equilibrium of the reaction shifts in the direction to counteract the change.
