Reaction Energy Diagram Endothermic Vs Exothermic. C draw a labeled enthalpy level diagram for an exothermic and endothermic reaction showing the activation energy ea and enthalpy change. In other words the products are less stable than the reactants.
In the case of an endothermic reaction the reactants are at a lower energy level compared to the products as shown in the energy diagram below. In endothermic reactions there is less energy in the reactants than in the products. A downwards arrow shows that energy is given out endothermic.
After viewing add two well labeled energy diagrams illustrating endothermic and exothermic.
An energy diagram can be used to show energy movements in these reactions and temperature can be used to measure them macroscopically. Energy level diagrams are used to shows the energy content of chemicals before and after a reaction. Therefore δh is positive. Endothermic and exothermic reactions paul andersen explains how heat can be absorbed in endothermic or released in exothermic reactions.
