A reaction coordinate is a parameter that represents progress along a reaction pathway, often visualized in a reaction coordinate diagram showing the energy changes as reactants transform into products. It helps in understanding the energy barrier, activation energy, and transition states involved in chemical reactions.

A reaction pathway is the step-by-step sequence of elementary reactions by which an overall chemical change occurs. Understanding these pathways helps in determining reaction mechanisms and optimizing conditions for desired products in chemical processes.

An energy barrier is a potential energy threshold that must be overcome for a chemical reaction or physical process to occur. It represents the activation energy required to initiate a transformation, influencing the rate and feasibility of reactions.

energy barrier

Activation energy is the minimum amount of energy required for a chemical reaction to occur, acting as a barrier that reactants must overcome to be transformed into products. Lowering the activation energy through catalysts increases the reaction rate without being consumed in the process.

activation energy

Transition states are high-energy configurations through which chemical reactions pass, representing the maximum energy point along the reaction pathway. Understanding transition states is crucial for predicting reaction rates and mechanisms, as they define the energy barrier reactants must overcome to form products.

transition states

Chemical reactions involve the transformation of substances through the breaking and forming of chemical bonds, resulting in the conversion of reactants into products. These reactions are governed by the principles of thermodynamics and kinetics, which dictate the feasibility and rate of these transformations.
