A free energy barrier is the energy difference that must be overcome for a chemical reaction or physical process to occur, acting as a threshold that determines the rate of the process. It is crucial in understanding reaction kinetics and mechanisms, as it influences the activation energy required for transitions between states.

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.

A threshold is a point or level at which a new state or condition is activated, often used to describe the minimum requirement needed to trigger a particular response or outcome. Understanding thresholds is crucial in fields ranging from psychology to environmental science, as they help define limits and tipping points that can lead to significant changes.

Reaction kinetics is the study of the rates at which chemical processes occur and the factors that influence these rates. It provides insights into the mechanisms of reactions, allowing for the prediction and control of reaction behavior in various conditions.

reaction kinetics

Reaction mechanisms describe the step-by-step sequence of elementary reactions by which overall chemical change occurs, providing insight into the detailed pathway and intermediate species involved. Understanding reaction mechanisms is crucial for predicting reaction behavior, optimizing conditions, and designing new chemical processes or materials.

Reaction Mechanisms

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.
