Chapter 3, Problem 73E

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 ${\text{H}}_{\text{2}}\text{S}\left(\text{g}\right)+3{\text{F}}_{\text{2}}\left(\text{g}\right)\to {\text{SF}}_{\text{4}}\left(\text{g}\right)+2\text{HF}\left(\text{g}\right)$.
