Chapter 18, Problem 25E

Interpretation Introduction

Interpretation:

The direction in which the equilibrium will shift for the reaction $2{\text{SO}}_2\left(\text{g}\right)+{\text{O}}_2\left(\text{g}\right)\rightleftharpoons 2{\text{SO}}_3\left(\text{g}\right)$ at equilibrium on decreasing the concentration of oxygen is to be predicted. The explanation for the answer is to be stated.

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.
