The natural environment is an open system, where chemical species can diffuse away. In such an environment, a mechanism to maintain the concentration of chemical species is required to stabilize chemical reaction networks such as prebiotic metabolism. In this study, we will propose autocatalysis as a potential mechanism to counter diffusion, and present several kinetic requirements necessary to stabilize the chemical reaction network. The kinetic requirement becomes more stringent when the number of species increases, implying the possibility of chemical evolution towards stronger amplification and slower dissipation.
