Chapter 3, Problem 78E

Interpretation Introduction

Interpretation: The bond energy of $\text{A}-\text{A}$ is to be determined for the given reactions.

Concept introduction: The bond energy is the energy required to break apart a compound.

Energy change of a reaction is defined as the sum of change in internal energy and the product of absolute temperature and entropy of system.

To determine: The value of bond energy of $\text{A}-\text{A}$ for the reaction ${\text{A}}_{\text{2}}+{\text{B}}_{\text{2}}\to 2\text{AB}$.
