Chapter 7, Problem 28P

Interpretation Introduction

(a)

Interpretation:

Whether the position of equilibrium will shift to right or left when some amount of ${\text{O}}_{\text{3}}$ is removed from the endothermic reaction (reaches equilibrium).

${\text{3O}}_{\text{2}}\text{(g)}◰\; \hspace{1em}{\text{2O}}_{\text{3}}\text{(g)}$

Concept Introduction:

When product is removed the equilibrium is shifted to product side.

Interpretation Introduction

(b)

Interpretation:

Whether the position of equilibrium will shift to right or left when some amount of ${\text{O}}_{\text{2}}$ is removed from the endothermic reaction (reaches equilibrium).

${\text{3O}}_{\text{2}}\text{(g)}◰\; \hspace{1em}{\text{2O}}_{\text{3}}\text{(g)}$

Concept Introduction:

When reactant is removed the equilibrium is shifted to reactant side.

Interpretation Introduction

(c)

Interpretation:

Whether the position of equilibrium will shift to right or left when some amount of ${\text{O}}_{\text{3}}$ is added from the endothermic reaction (reaches equilibrium).

${\text{3O}}_{\text{2}}\text{(g)}◰\; \hspace{1em}{\text{2O}}_{\text{3}}\text{(g)}$

Concept Introduction:

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

Interpretation Introduction

(d)

Interpretation:

Whether the position of equilibrium will shift to right or left when temperature is decreased for the following equilibrium.

${\text{3O}}_{\text{2}}\text{(g)}◰\; \hspace{1em}{\text{2O}}_{\text{3}}\text{(g)}$

Concept Introduction:

When temperature is decreased for an exothermic reaction then the equilibrium is shifted to product side.

Interpretation Introduction

(e)

Interpretation:

Whether the position of equilibrium will shift to right or left after a catalyst is added for the following equilibrium.

${\text{3O}}_{\text{2}}\text{(g)}◰\; \hspace{1em}{\text{2O}}_{\text{3}}\text{(g)}$

Concept Introduction:

When catalyst is added then activation energy is reduced and thus equilibrium is attained faster.

Interpretation Introduction

(g)

Interpretation:

Whether the position of equilibrium will shift to right or left when pressure is increased for the following equilibrium.

${\text{3O}}_{\text{2}}\text{(g)}◰\; \hspace{1em}{\text{2O}}_{\text{3}}\text{(g)}$

Concept Introduction:

When pressure is increased for a reversible reaction then the equilibrium is shifted to less mole side.
