Energy Diagram Chemistry Exothermic. This chemistry video tutorial focuses on potential energy diagrams for endothermic and exothermic reactions. For the reaction is positive i e energy is absorbed from the surroundings.
The energy level of the products is lower than that of the reactants. This tells us that the change in standard gibbs free energy for the reaction δ g rnx is negative. The figure below shows basic potential energy diagrams for an endothermic a and an exothermic b reaction.
First let s review what this energy diagram tells us about the thermodynamics of the reaction illustrated by the energy diagram above.
Thus the products formed have less energy than the reactants h products h reactants. This tells us that the change in standard gibbs free energy for the reaction δ g rnx is negative. Thus the products formed have less energy than the reactants h products h reactants. An energy level diagram shows whether a reaction is exothermic or endothermic.
