The standard Gibbs free energy of formation, \(\Delta G^\circ_f\), is defined as the change in Gibbs free energy when \(1\text{ mol}\) of a substance in its standard state is formed from its constituent elements in their standard states at \(298\text{ K}\) and \(1\text{ atm}\). Which of the following balanced chemical equations represents the process for which \(\Delta G^\circ_{\text{rxn}} = \Delta G^\circ_f\) for liquid ethanol, \(\text{C}_2\text{H}_5\text{OH}(l)\)?
