Chapter 14, Problem 25CI

Interpretation Introduction

(a)

Interpretation:

The equilibrium constant for the reaction needs to be calculated.

Concept Introduction:

An equilibrium reaction can be shown with the help of equilibrium constant Kc. It is can be expressed as:

  $\text{Kc = }\frac{\text{[Product] }}{\text{[Reactant]}}$

Le Chatelier's principle states that when we change any one of the reaction conditions the reaction tends to move to minimize the effect of change. Hence it will move in that direction which can reduce the effects of changes.

Interpretation Introduction

(b)

Interpretation:

The change in the equilibrium due to addition of hydrogen gas needs to be determined.

Concept Introduction:

An equilibrium reaction can be shown with the help of equilibrium constant Kc. It is can be expressed as:

  $\text{Kc = }\frac{\text{[Product] }}{\text{[Reactant]}}$

Le Chatelier's principle states that when we change any one of the reaction conditions the reaction tends to move to minimize the effect of change. Hence it will move in that direction which can reduce the effects of changes.

Interpretation Introduction

(c)

Interpretation:

The shift in the equilibrium if the volume of the container changes to 5.00 L keeping temperature constant needs to be explained.

Concept Introduction:

An equilibrium reaction can be shown with the help of equilibrium constant Kc. It is can be expressed as:

  $\text{Kc = }\frac{\text{[Product] }}{\text{[Reactant]}}$

Le Chatelier's principle states that when we change any one of the reaction conditions the reaction tends to move to minimize the effect of change. Hence it will move in that direction which can reduce the effects of changes.

Interpretation Introduction

(d)

Interpretation:

The concentration of ${\text{S}}_{\text{2}}$ needs be determined if the temperature remains the same.

Concept Introduction:

An equilibrium reaction can be shown with the help of equilibrium constant Kc. It is can be expressed as:

  $\text{Kc = }\frac{\text{[Product] }}{\text{[Reactant]}}$

Le Chatelier's principle states that when we change any one of the reaction conditions the reaction tends to move to minimize the effect of change. Hence it will move in that direction which can reduce the effects of changes.
