Answer : The answer is, Chain reaction.
Explanation :
Chain reaction : It is defined as the series of successive elementary processes in which the active intermediate species are consumed and regenerated before the products are obtained.
It is a self-sustaining series of the chemical reactions where the product obtained from one reaction are the reactants in the next reaction and so on.
Hence, a chain reaction is a self-sustaining series of chemical reactions in which the product of one reaction are the reactants in the next reaction.
