Chapter 12, Problem 67QRT

(a)

Interpretation Introduction

Interpretation:

For the given reaction at equilibrium, whether the reverse or the forward reaction rate is faster after adding some of ${\text{HBr}}_{\text{(g)}}$ without changing the total volume has to be given.

Concept Introduction:

Le Chatelier's principle:

It states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.

(b)

Interpretation Introduction

Interpretation:

For the given reaction at equilibrium, whether the reverse or the forward reaction rate is faster after removing some of ${\text{Br}}_{\text{2(g)}}$ without changing the total volume has to be given.

(c)

Interpretation Introduction

Interpretation:

For the given reaction at equilibrium, whether the reverse or the forward reaction rate is faster when system’s total volume is halved has to be given.
