If a reaction is exothermic, it means that heat is released during the reaction. When there is a great disorder, it means that the reactants have high entropy, or in other words, they are disordered. In general, exothermic reactions tend to favor products that are in a lower energy state than the reactants, while high entropy favors products that are in a more disordered state. Therefore, if a reaction is exothermic and there is a great disorder, it means that the reactants have high entropy, but the products have lower energy than the reactants. As a result, the reaction will proceed spontaneously towards the products, releasing heat in the process. Therefore, the correct option is: "There will be a large decrease in free energy."
