Energy barriers are potential energy thresholds that must be overcome for a chemical reaction or physical process to occur, often determining the rate and feasibility of these processes. They play a crucial role in kinetics and thermodynamics, influencing reaction pathways and the stability of reactants and products.

A chemical reaction is a process where substances, known as reactants, are transformed into different substances, called products, through the breaking and forming of chemical bonds. This transformation involves changes in energy and is governed by the principles of conservation of mass and energy.
