Interpretation Introduction

Interpretation:

The symbols for ∆G⁰ for the given conditions are to be filled.

Concept introduction:

The sign of standard free energy change gives the direction of spontaneity of the reaction.

If the free energy change is negative $\left(\Delta G^{\circ }<0\right)$, the reaction is spontaneous. It means that the formation of products is favored.

If the free energy change is positive $\left(\Delta G^{\circ }>0\right)$, the reaction is non-spontaneous. In such cases, the formation of reactants is favored.

When $\Delta {\text{G}}^{\text{0}}\text{ = 0}$ the reaction is in equilibrium

The expression for standard free energy change is as follows:

$\Delta G^{\circ }=-RT\ln K$

Here, $R$ is the ideal gas constant and $T$

is the temperature.
