Chapter 18, Problem 37E

Interpretation Introduction

Interpretation:

Whether the highest or lowest temperature possible is used to increase the yield of ${\text{SO}}_3$ in the equilibrium ${\text{SO}}_2\left(\text{g}\right)+{\text{NO}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons {\text{SO}}_3\left(\text{g}\right)+\text{NO}\left(\text{g}\right)+41.8\text{kJ}$ is to be predicted.

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.
