Chapter 16.3, Problem 16.6P

(a)

Interpretation Introduction

Interpretation:

Shift of equilibrium with increase in temperature in below reaction has to be determined.

  $2{\text{SO}}_2\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)\rightleftharpoons 2{\text{SO}}_{\text{3}}\left(g\right)+198\text{ kJ}$

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. According to this principle with increase in temperature reaction rate rises due to rise in kinetic energy. In case of endothermic reaction that is when energy is absorbed then the reaction moves in forward direction. In case of exothermic reaction that is when energy is released then reaction moves in backward direction.

(b)

Interpretation Introduction

Interpretation:

Shift of equilibrium with increase in temperature in below reaction has to be determined.

  ${\text{H}}_{\text{2}}\left(g\right)+{\text{CO}}_{\text{2}}\left(g\right)+41\text{ kJ}\rightleftharpoons {\text{H}}_{\text{2}}\text{O}\left(g\right)+\text{CO}\left(g\right)$
