Endothermic Energy Diagram. In other words the products are less stable than the reactants. An endothermic process is any process with an increase in the enthalpy h or internal energy u of the system.
There is a greater difference in energy between the reactants and products. The activation energy is the energy that must be provided to the reactants so that they can overcome the energy barrier and react. For exothermic reactions the potential energy of the product is generally lower than that of the reactant.
Kj and the reaction is endothermic.
If you had an endothermic reaction a simple energy profile for a non catalysed reaction would look like this. It may be a chemical process such as dissolving ammonium nitrate in water or a physical process such as the melting of ice cubes. Energy level diagram of an endothermic reaction. An energy diagram can be used to show energy movements in these reactions and temperature can be used to measure them macroscopically.
