Chapter 16.6, Problem 16.10CE

(a)

Interpretation Introduction

Interpretation:

Whether the same method can be used to estimate the Gibbs free energy is to be predicted with an explanation.

Concept Introduction:

The Gibbs free energy of the system represents the maximum amount of non-expansion work achieved by a thermodynamic system at isothermal and isobaric conditions.  The change in Gibbs free energy is used to predict the spontaneous of the process.  Standard Gibbs free energy of the reaction is an extensive property.

(b)

Interpretation Introduction

Interpretation:

At $\text{400 °C}$, whether the reaction would be more or less product-favored in comparison to $\text{350 °C}$ is to be stated.

Concept Introduction:

A chemical process can be categorized as reactant-favored or product-favored.  It depends upon the concentration of products and reactants at the stage of equilibrium.  If products predominated over reactants, then it called product-favored process.  If reactants are predominated over products, then it is called reactant-favored process.
