The task involves using given data to calculate the values of ΔG°_rxn at 25 °C for the reaction described by the equation: \[ A + B \rightleftharpoons C \] A table is provided with the standard Gibbs free energy of formation (ΔG°_f) for each compound: | Compound | ΔG°_f (kJ/mol) | |----------|----------------| | A | +387.7 | | B | +613.4 | | C | +402.0 | To calculate ΔG°_rxn, use the equation: \[ \Delta G^\circ_{rxn} = \sum \Delta G^\circ_f (\text{products}) - \sum \Delta G^\circ_f (\text{reactants}) \] Fill the blank with the calculated value: \[ \Delta G^\circ_{rxn} = \_\_\_\_ \text{kJ} \] Additionally, if both ΔH°_rxn and ΔS°_rxn are negative, evaluate what drives the spontaneous reaction and in which direction at standard conditions. Choose from the following options: - \( \bigcirc \) entropy-driven to the left. - \( \bigcirc \) entropy-driven to the right. - \( \bigcirc \) enthalpy-driven to the left. - \( \bigcirc \) enthalpy-driven to the right.
