Chapter 16, Problem 122QRT

Interpretation Introduction

Interpretation:

The way in which ${\Delta }_{\text{r}}\text{H}°$ and ${\Delta }_{\text{r}}\text{S}°$ can be predicted from the given has to be stated with the help of the equation ${\Delta }_{r}G°=-RT\ln K°$. Whether the straight line of the corresponding graph predicts any relation of ${\Delta }_{\text{r}}\text{H}°$ and ${\Delta }_{\text{r}}\text{S}°$ with temperature or not is to be stated. The corresponding anwer has to be explained.

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.
