WebApr 30, 2024 · For an exothermic reaction, heat is essentially a product of the reaction. In keeping with Le Chatelier's principle, if you increase the temperature you are increasing the amount of products, and so you shift the balance at equilibrium back toward reactants, meaning there will be more reactants left at equilibrium. WebMay 27, 2024 · What is exothermic reactions? Exothermic reactions are those reactions in which heat is produced at the end or after completion of the reaction. Heat will not wriiten as a reactant because heat is not the entity which produces products.
