Interpretation Introduction

To determine: The change in free energy of the given reaction by increasing temperature.

(b)

Interpretation Introduction

To determine: The free energy change of the given reaction at $800\text{K}$ assuming $\Delta H^0$ and $\Delta S^0$ do not change with temperature; also the spontaneity of the reaction.

(c)

Interpretation Introduction

To determine: The free energy change of the given reaction at $1000\text{K}$ assuming $\Delta H^0$ and $\Delta S^0$ do not change with temperature and the spontaneity of the reaction.
