WebDecomposition reactions can be exothermic or endothermic, depending on the chemical energy of the substances. If the chemical energy of reactants are greater than products that time the reaction is exothermic with negative ( ΔH) and at that time, the product is more stable than reactant. Webexothermic: 1 adj (of a chemical reaction or compound) occurring or formed with the liberation of heat Synonyms: exothermal , heat-releasing energy-releasing , exoergic (of a nuclear reaction) occurring with evolution or releasing of energy Antonyms: endothermal , endothermic , heat-absorbing (of a chemical reaction or compound) occurring or ...

WebGibbs free energy and spontaneity. When a process occurs at constant temperature \text T T and pressure \text P P, we can rearrange the second law of thermodynamics and define a new quantity known as Gibbs free energy: \text {Gibbs free energy}=\text G =\text H - \text {TS} Gibbs free energy = G = H − TS. Web2 days ago · 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.
