Chapter 17, Problem 31E

Interpretation Introduction

Interpretation:

The standard enthalpy change, standard entropy change, standard free energy and the spontaneity of the reaction of the given reaction is to be stated and the changes that should be done to change a non-spontaneous reaction into spontaneous is to be identified.

Concept introduction: The standard free energy, $\Delta G°$ , of the reaction is calculated as,

$\Delta G°=\text{Enthalpy}\text{change}-\text{Absolute}\text{temperature}\times \text{Entropy}\text{change}$

The reaction is spontaneous for the negative value of standard free energy of the reaction.

To determine:The standard enthalpy change, standard entropy change, standard free energy, the spontaneity of the reaction of the given reaction and the changes that should be done to change a non-spontaneous reaction into spontaneous reaction.
