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). By examining this enthalpy change, one can tell whether a reaction is endothermic (ΔH>0) or exothermic (ΔH<0). Energy From Chemicals - Enthalpy Change - Difference ... Energy Profile diagrams: Energy profile diagrams are used to represent the energy pathway from reactants to products in a reaction. The energy profile diagram for exothermic reaction show that the reactants have higher initial energy and products have lower energy since the energy has been given out during the reaction.
