Definition: The term "accelerant" refers to a substance that increases the rate of chemical reactions or physical changes, such as combustion, oxidation, and reaction with a catalyst. Accelerants are often used in the field of chemistry to accelerate the formation of products during chemical reactions. In general, accelerants can be characterized by having a high activation energy (more energy required for a specific change than that needed for a more simple one), or a low activation energy (less energy is required to cause a reaction). Examples of accelerants include: - Carbon monoxide: used as an oxidant in the combustion of organic compounds. - Nitrogen dioxide: used as an oxidant in the oxidation of sulfuric acid, which produces water and carbon dioxide. - Helium peroxide: used as an oxidizing agent to speed up the reaction between magnesium and water. The specific definition of a "accelerant" can vary depending on context. However, generally speaking, accelerants are substances that contribute to chemical reactions with energy to increase the rate at which those reactions occur. In summary, accelerants are substances that increase the activation energies for chemical reactions or physical changes, such as combustion, oxidation, and reaction with a catalyst. They can be characterized by their high activation energies (more energy required for a specific change than is necessary for a more simple one) or their low activation energies (less energy is needed to cause a reaction).
