How do you know if a diagram is endothermic or exothermic ... 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). How to tell if a reaction is exothermic or endothermic ... Basically, melting ice is an endothermic reaction because the ice absorbs (heat) energy, which causes a change to occur. Is Melting endothermic or exothermic?

Endothermic Reaction Energy Level Diagram: Endothermic reactions are depicted in a basic energy level diagram below. The activation energy is the amount of energy that must be delivered to the reactants for them to break through the energy barrier and react. In an endothermic reaction, the result has higher potential energy than the reactants. PDF Potential Energy Diagrams ENDOTHERMIC OR EXOTHERMIC? Note the REACTANTS and PRODUCTS are labeled. The reactants are higher in energy (higher on y axis) then products, indicating energy is released (lost) as chemical reaction occurs, so this is an exothermic reaction. ΔH is the total energy change (enthalpy) of the reaction. ΔH is the difference in energy between the
