Autocatalytic is a term that describes a chemical reaction in which the product of the reaction acts as a catalyst to increase the rate of the reaction. Synonyms for this word include self-catalyzing, self-amplifying, self-enhancing, and self-propagating. The term autocatalytic is commonly used in the fields of chemistry, biology, and technology to describe processes that exhibit exponential growth and amplification. Other synonyms for autocatalytic include self-perpetuating, self-regenerating, and self-sustaining. The concept of autocatalysis is important in understanding complex systems and the emergence of patterns and structures in nature, which has many practical applications in industry and science.
