The reaction shown below is used in the production of steel. It is an exothermic reaction. An engineer thinks that by finding the correct catalyst, he can reduce the amount of energy released by the reaction. Will his plan have the desired effect? Why or why not? Fe3O4(s) + 4C(s) → 3Fe(s) + 4CO(g)

Yes, because the reaction is already exothermic, so any added reactants will lower the amount of energy released.
Yes, because the catalyst should add energy, thereby reducing the energy released.
No, because catalysts always increase the amount of energy released by reactions.
No, because catalysts do not affect how much energy is released, only the rate of reaction.
