Chapter 18, Problem 6PE

Interpretation Introduction

Interpretation:

The direction of the reaction, ${\text{2SO}}_2\left(\text{g}\right)+{\text{O}}_2\left(\text{g}\right)\rightleftharpoons 2{\text{SO}}_3\left(\text{g}\right)+198\text{kJ}$ at equilibrium when the temperature of the system is decreased is to be predicted.

Concept introduction:

Equilibrium is the state where the concentration of the reactant is equal to the concentration of the product. According to Le Chatelier’s Principle, the equilibrium shifts in such a way or a direction that it can reduce the effect of change.
