Chapter 21, Problem 21.35SP

Interpretation Introduction

Interpretation:

The values of $\Delta H^o$ and $\Delta G^o$ for the reaction has to be determined and reason for $\Delta H^o$ and $\Delta G^o$ have different values has to be explained and sign of $\Delta H^o-\Delta G^o$ has to be accounted.

Concept introduction:

• Enthalpy change of the reaction is the sum of enthalpy change of the product minus the sum of enthalpy change of the reactant.
• $\Delta G^o=\Delta H^o-T\Delta S^o$, where $\Delta G^o$, the change in standard Gibbs free energy , $\Delta H^o$ is the change in standard enthalpy $\Delta S^o$ is the change in standard entropy and $T$ is the temperature in kelvin.
