Chapter 7, Problem 7.39P

Interpretation Introduction

(a)

Interpretation:

Whether the position of equilibrium will shift to right or left when some amount of ${\text{Br}}_{\text{2}}$ added to the following reaction (after reaches equilibrium).

${\text{2NO(g)+Br}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2NOBr(g)}$

Concept Introduction:

When reactant is added, the equilibrium is shifted to product side.

Interpretation Introduction

(b)

Interpretation:

What will happen to equilibrium constant when some amount of ${\text{Br}}_{\text{2}}$ is added to the following equilibrium.

${\text{2NO(g)+Br}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2NOBr(g)}$

Concept Introduction:

When reactant is added, the equilibrium is shifted to product side but there is no change of equilibrium constant.
