Dominant Region Analysis: A Novel Framework for Quantifying Competitive Reactions Based on the Gillespie Algorithm

Understanding the quantitative relationships between competing reactions is crucial for analyzing chemical reaction systems.While conventional approaches often focus on static analysis, we propose a novel concept called "dominant region" to capture the dynamic nature of reaction competition.The dominant region concept can be viewed as an extension of the traditional rate-determining step in reaction kinetics.This enables quantitative prediction of how dominant reactions dynamically change with variations in reactant concentrations.
