WebJan 30, 2024 · A reaction in which heat energy is given off is said to be exothermic. A reaction in which heat energy is absorbed is said to be endothermic. You can show this on simple energy diagrams. For an exothermic change: Notice that in an exothermic change, the products have a lower energy than the reactants. WebWhether it does one or the other depends on the enthalpy change; whether it is endothermic or exothermic. If a reaction is endothermic, where heat is absorbed as the reaction progresses from reactants to products, then increasing the temperature will increase the equilibrium constant. The opposite is true if a reaction is exothermic. ios wireframe template
