On an energy profile diagram, what is true regarding the reactant and product energy levels for both catalyzed and uncatalyzed reactions?
Answer
The starting energy level (Reactants) and final energy level (Products) are the same for both
Since the overall energy difference ($\Delta H$) is unchanged, the initial energy state of the reactants and the final energy state of the products must align for both pathways when plotted on the same energy profile diagram.
