Problem: Calculate the standard change in Gibbs free energy for the following reaction at 25 °C. 6Cl2(g) + 2Fe2O3 (s) → 4FeCl3(s) + 3O2(g)

FREE Expert Solution

The standard free energy change of a reaction (ΔG˚rxn) is given by the following equation:


G°rxn = H°rxn - TS°rxn


The balanced equation is:

6Cl2(g) + 2Fe2O3 (s) → 4FeCl3(s) + 3O2(g)


We are going to do the following steps:

Step 1: Calculate ΔH°rxn

Step 2: Calculate  ΔS°rxn 

Step 3: Calculate ΔG°rxn
