Final answer:
To calculate the standard molar Gibbs free energy (ΔGº) for the reaction at 25°C, you need to know the temperature, the standard entropy change (ΔS°), and the standard enthalpy change (ΔH°) for the reaction. You can calculate ΔS° using the absolute molar entropy values given for the reactants and products, and then use them to find ΔGº using the equation ΔGº = ΔHº - TΔSº.
Step-by-step explanation:
To calculate the standard molar Gibbs free energy (ΔGº) for the reaction at 25°C, you need to know the temperature, the standard entropy change (ΔS°), and the standard enthalpy change (ΔH°) for the reaction. The equation to calculate ΔGº is: ΔGº = ΔHº - TΔSº, where T is the temperature in Kelvin. Using the absolute molar entropy values given for the reactants and products, you can calculate ΔS° using the 'products minus reactants' rule. Then, using the temperature and calculated ΔS°, you can plug them into the equation to find ΔGº.
