If energy is absorbed is it endothermic
Web27 jan. 2024 · Energy diagrams, also known as potential energy diagrams, can be used to represent the energy changes that occur during a chemical reaction. These diagrams show the potential energy of the reactants and products, as well as the activation energy required for the reaction to occur. The diagrams also indicate whether a reaction is endothermic … WebThe internal energy of a chemical system is the sum of its kinetic energy and its potential energy. It is this potential energy that absorbs the energy in an endothermic chemical reaction. In an endothermic reaction, as some bonds break and others form, the protons and electrons go from an arrangement of lower potential energy to one of higher …
