Chapter 4, Problem 8RQ

Summary Introduction

To review:

The temperature at which standard free energy ( $\Delta G\text{°'}$ )is equal to the enthalpy change( $\Delta H$ ) for all the conditions.

Introduction:

A system’s enthalpy is the sum total of the internal energy, and the product of pressure and volume of the system. It is a state function, which means it is defined by the state of the system only. $\Delta H$ is the amount of heat that a system absorbs or releases when a reaction takes place at a constant pressure, and $\Delta G\text{°}$ is the free energy at standard conditions of temperature.
