Energy in chemical reaction

WebActivation energy is the amount of added energy required to reach the midpoint of a chemical reaction. Activation energy is the level of energy in the reactants of a reaction. Activation energy is the level of energy in the products of a reaction. Enzymes work to increase the activation energy required for a biochemical reaction. WebAn energy profile shows how the energy of a system changes as the reaction progresses. It is synonymous with an energy diagram/energy profile diagram. As stated previously, the energy profile diagram follows the change in potential energy. The y-axis is the potential energy and the x-axis is the reaction coordinate/reaction progress.
