WebbAn Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light. These reactions are the opposite of endothermic reactions and can be expressed in a chemical equation as follows: Reactants → Products + Energy What is an Exothermic Reaction? WebbThe activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be.

"WebbIt provides useful energy that is released in an exothermic reaction. It stops the products from being formed from the intermediate state. It slows down the overall chemical reaction so it does not happen too quickly. It provides reactants with sufficient energy for bonds to break and reform. " - Slow exothermic reaction graph

Webb24 apr. 2024 · The forward rxn (left to right as you face it) was clearly EXOTHERMIC. To go from right to left, we have to input energy into the system: the energy that was released from the forward reaction PLUS the original energy of activation. I think it is fairly clear from such a graph as to the energy requirements of the reaction. Answer link. Webb2 maj 2024 · In an endothermic reaction, activation potential energy of reactants is less than that of the products.Reactants in endothermic reaction are absorbing enough heat energy to overcome this barrier potential.
