Chapter 18, Problem 1PE

Interpretation Introduction

Interpretation:

For the reaction ${\text{N}}_2\left(\text{g}\right)+{\text{O}}_2\left(\text{g}\right)\rightleftharpoons 2\text{NO}\left(\text{g}\right)$, the direction in which equilibrium will shift if oxygen is removed from the reaction container is to be stated.

Concept introduction:

A reaction is said to be in equilibrium if the rate at which the forward reaction takes place becomes equal to the rate at which the backward reaction takes place. If any of the factors that affect the equilibrium changes, then the reaction shifts in either forward or backward direction so that the equilibrium condition is reestablished.
