What is the definition of exothermic reaction in chemistry?
An 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 a exothermic easy definition?
Definition of exothermic : characterized by or formed with evolution of heat.
What is the definition of endothermic reaction in chemistry?
Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.
Which answer defines exothermic reaction?
Which answer defines exothermic reaction? a process in which energy is released as heat.
What do you mean by exothermic reaction and endothermic reactions?
The chemical reactions that release heat energy are called exothermic reactions. Example: C(g)+O2(g)→CO2(g)+Heat Energy. The chemical reactions in which heat energy is absorbed are called endothermic reactions.
What is exothermic and endothermic reactions?
An exothermic process is one that gives off heat. This heat is transferred to the surroundings. An endothermic process is one in which heat has to be supplied to the system from the surroundings. A thermoneutral process is one that neither requires heat from the surroundings nor gives off energy to the surroundings.
What are endothermic and exothermic reactions?
What is exothermic reaction Class 10 with example?
What is an Exothermic Reaction? A reaction that is chemical in nature and is characterized by the release of energy in the form of heat or light is called an exothermic reaction. Matching a light using a matchstick is one example of this type of reaction where the release is in the form of both heat and light.
What is exothermic reaction Class 11?
Exothermic reactions are those reactions in which heat is released. Reactants→products+heat. For example, formation of ammonia from nitrogen and hydrogen is an exothermic reaction. N2(g)+3H2(g)→2NH3(g)+92.
