Chapter 9, Problem 31E

Interpretation Introduction

Interpretation: The reason for the need of high temperature for the following reaction should be determined:

  ${\text{N}}_{\text{2}}{\text{(g)+O}}_{\text{2}}\text{(g)}\to \text{2NO(g) }\Delta \text{H = 180 kJ}$

Concept Introduction: Endothermic and exothermic processes are defined on the basis of energy involved. The addition of energy is endothermic whereas loss of energy is exothermic.
