Chapter 8, Problem 71E

Interpretation Introduction

Interpretation: The change in energy $\Delta E$ is to be determined from bond energy values 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 energy change $\Delta E$ for the reaction ${\text{CH}}_{\text{3}}\text{N}\equiv \text{C}\left(\text{g}\right)\to {\text{CH}}_{\text{3}}\text{C}\equiv \text{N}\left(\text{g}\right)$.
