The Arrhenius equation is a mathematical equation that describes the relationship between temperature, activation energy, and reaction rate. This fundamental equation has been widely used in chemistry, physics, and engineering fields. Synonyms for the Arrhenius equation include the temperature-rate equation, activation energy equation, and thermal activation equation. Other related terms include the Boltzmann factor, the Gibbs free energy, and the thermodynamic barrier. The use of these synonyms can help scientists and researchers communicate more effectively, enabling them to better understand and analyze many types of chemical and physical processes.
