Chapter 7.7, Problem 7.6P

Interpretation Introduction

Interpretation:

The effect on the equilibrium reaction when ${\text{Br}}_{\text{2}}$ gas is added to the equilibrium mixture should be explained.

Concept Introduction:

Chemical equilibrium:

A chemical equilibrium shifted towards forward direction or backward direction depend on the concentration of both reactant or products. According to Le Chatelier’s principle, to any change in the equilibrium reaction, the equilibrium will shift in such a direction to overcome that change.

Let the equilibrium reaction be:

$\text{a}\text{a}+bB◰\; \hspace{1em}\text{C}\text{C}+dD$

Here, A and B are reactants and C and D are products. Also, a, b, c and d are coefficient of A, B, C and D respectively.
