Chapter 3, Problem 75E

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 is defined as the sum of change in internal energy plus product of the system.

To determine: The value of energy change $\Delta E$ for the reaction ${\text{C}}_2{\text{H}}_2\left(\text{g}\right)+\frac{5}{2}{\text{O}}_2\left(\text{g}\right)\to 2{\text{CO}}_2\left(\text{g}\right)+{\text{H}}_2\text{O}\left(\text{g}\right)$
