Exothermic Reaction Definition - ThoughtCo
WebJan 16, 2024 · An exothermic reaction is a chemical reaction that produces heat (has a negative ΔH). In other words, the activation energy needed to initiate the reaction is less than the energy it releases. Examples of exothermic reactions include neutralization reactions, the Haber process, the thermite reaction, and combustion reactions. Web1. Draw a potential energy graph for an endothermic and exothermic reaction. What can be said about how the energy of the products compares to the energy of the reactants in each graph? On endothermic graphs, the products will always come out to be higher than the reactants, on exothermic graphs, the products will have a lower outcome than the … nait architectural technology
