In case of autocatalysis
WebAutocatalysis definition, catalysis caused by a catalytic agent formed during a reaction. See more. WebAuto Catalysis : When one of the reaction product behave as catalyst for that reaction and increase the rate of reaction then the phenomenon is called autocatalysis. Auto catalytic reactions are slow in the beginning but become increasingly rapid as the reaction proceeds.

The second law of thermodynamics states that the disorder (entropy) of a physical or chemical system and its surroundings (a closed system) must increase with time. Systems left to themselves become increasingly random, and orderly energy of a system like uniform motion degrades eventually to the random motion of particles in a heat bath.
