Abstract: It is well known that the dynamic behavior of chemical reactions in fractional or low dimension medium is greatly different from that ruled by the classical chemical dynamics.In this paper,the anomalous dynamic behavior of trimolecular reaction Xin one dimension medium is studied.Anew theoretical method is developed,by which an analytical solution to the dynamic behavior of this reaction under different initial conditions is obtained.In addition,this new method is verified by the results based on some numerical simulations.

Key words: One dimension medium, Trimolecular reaction, Chemical kinetics
