Answer: A potential energy diagram shows the reaction progressing from left to right, as indicated by the arrow on the bottom. So, the reactants are on the left and the products are on the right. The activated complex is at the highest potential energy in the reaction. The level where the reactants start is the energy level of the reactants. Similarly, the level where the products end up is the energy level of the products. These energy levels are indicated by arrows. The activation energy is the difference between the energy of the activated complex and the energy of the reactants. The energy released by the reaction is the difference of the energy of the reactants and the energy of the products.
