Question

Calculate the standard change in Gibbs free energy for the reaction at 25 °C. Standard Gibbs free energy of formation values can be found in this table. Fe₂⁺O₃(s) + 2Al(s) Ÿ¶ Al₂O₃(s) + 2Fe(s)?

Answer 1

To calculate the standard change in Gibbs free energy for this reaction, use the formula ΔG° = ΣΔG°(products) - ΣΔG°(reactants) and find the standard Gibbs free energy of formation values for the reactants and products.

Step-by-step explanation:

To calculate the standard change in Gibbs free energy for this reaction, use the formula ΔG° = ΣΔG°(products) - ΣΔG°(reactants) and find the standard Gibbs free energy of formation values for the reactants and products. To calculate the standard change in Gibbs free energy for the reaction Fe₂⁺O₃(s) + 2Al(s) Ÿ¶ Al₂O₃(s) + 2Fe(s) at 25 °C, we need to use the formula ΔG° = ΣΔG°(products) - ΣΔG°(reactants).

We can find the standard Gibbs free energy of formation values for the reactants and products in a table. Substituting the values into the formula and solving will give us the standard change in Gibbs free energy for the reaction at 25 °C.
