Interpretation Introduction

Introduction: The change in Gibbs free energy $\Delta G_{\text{rxn}}^{°}$ can be calculated by the following equation:

$\Delta G_{\text{rxn}}^{°}=\Delta H_{\text{rxn}}^{°}-T\Delta S_{\text{rxn}}^{°}$

Here, $\Delta H_{\text{rxn}}^{°}$ is enthalpy change of the reaction, $\Delta S_{\text{rxn}}^{°}$ is entropy change of the reaction, and T is the temperature.
