PDF Potential Energy Diagrams the diagrams graphically compare reactant energy to product energy as reaction occurs if reactants have more energy then products, the reaction is exothermic (loss of energy) if reactants have less energy then products, the reaction is endothermic (gain of energy) How do you know if a diagram is endothermic or exothermic ... 14/03/2019 · How do you know if a diagram is endothermic or exothermic? In the energy level diagram, the enthalpies of the products are lower than that of the reactants. Hence, the enthalpy change is negative (ΔH 0) or exothermic (ΔH Energy Diagrams | OpenOChem Learn The rate of a reaction is governed by its Activation Energy or Activation Barrier (E a). The activation energy (E a) is the difference in energy the reactants and transition state complex. To go from reactants to products you must go over the activation barrier. Endothermic Reactions Reactions that absorb heat are termed endothermic. In an endothermic reaction ...
