Chapter 7, Problem 27P

Interpretation Introduction

(a)

Interpretation:

Whether the position of equilibrium will shift to right or left when some amount of $\text{HI}$ is removed from the following equilibrium.

${\text{H}}_{\text{2}}{\text{(g)+I}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2HI(g)}$

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 ${\mathrm{I}}_2$ is added to the following equilibrium.

${\text{H}}_{\text{2}}{\text{(g)+I}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2HI(g)}$

Concept Introduction:

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

Interpretation Introduction

(c)

Interpretation:

Whether the position of equilibrium will shift to right or left when some amount of ${\mathrm{I}}_2$ is removed from the following equilibrium.

${\text{H}}_{\text{2}}{\text{(g)+I}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2HI(g)}$

Concept Introduction:

When reactant is removed 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 increased for the following equilibrium.

${\text{H}}_{\text{2}}{\text{(g)+I}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2HI(g)}$

Concept Introduction:

When temperature is increased for an endothermic reaction then the equilibrium is shifted to the 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.

${\text{H}}_{\text{2}}{\text{(g)+I}}_{\text{2}}\text{(g)}◰\; \hspace{1em}\text{2HI(g)}$

Concept Introduction:

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