Chapter 8, Problem 72E

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 ${\text{CH}}_4\left(\text{g}\right)+2{\text{O}}_2\left(\text{g}\right)\to {\text{CO}}_2\left(\text{g}\right)+2{\text{H}}_2\text{O}\left(\text{g}\right)$
