Chapter 16.3, Problem 16.5P

(a)

Interpretation Introduction

Interpretation:

Effect of equilibrium on below reaction as volume of container’s decreases has to be determined.

  $\text{2NO}\left(g\right)+{\text{Cl}}_{\text{2}}\left(g\right)\rightleftharpoons \text{2NOCl}\left(g\right)$

Concept Introduction:

Le Chatelier’s principle states that changes at equilibrium in system respond to reduce the changes and bring back the system to restore its equilibrium under new conditions. Change in volume affects rate of reaction only for the gaseous molecules. With change in volume pressure also changes and equilibrium shifts towards that side that has less number of moles of gaseous atoms to reduce the affect.

(b)

Interpretation Introduction

Interpretation:

Effect of equilibrium on below reaction as volume of container’s decreases has to be determined.

  ${\text{2COBr}}_2\left(g\right)\rightleftharpoons \text{2CO}\left(g\right)+{\text{Br}}_{\text{2}}\left(g\right)$

Concept Introduction:

Refer to part (a).
