Chapter 6, Problem 6.29NP

Interpretation Introduction

Interpretation : The value of $\Delta G^0$ for the process $\left({\text{H}}_2\text{O, g, 298 K}\right)\to \left({\text{H}}_2\text{O, g, 600 K}\right)$ should be calculated and the relative change in the Gibbs energy should be calculated.

Concept Introduction :

Gibbs-Helmholtz equation is represented as follows:

  $\Delta G(T_2)=T_2\left[\frac{\Delta G(T_1)}{T_1}+\Delta H_f^0(T_1)\left(\frac{1}{T_2}-\frac{1}{T_1}\right)\right]$

Here,

  $\begin{array}{l}\Delta G\text{ - Gibbs free energy change}\\ \text{T - temperature}\\ \Delta H_f^0\text{ - enthalpy change}\end{array}$
