Eyringyhtälö
Eyringyhtälö, also known as the Eyring equation or Eyring-Polanyi equation, is a fundamental equation in chemical kinetics that relates the rate of a chemical reaction to the properties of the transition state. Developed by Henry Eyring, Michael Polanyi, and Meredith G. Evans, it provides a theoretical framework for understanding reaction rates based on thermodynamics. The equation is derived from transition-state theory, which postulates the existence of a high-energy intermediate structure called the transition state or activated complex.
The Eyring equation expresses the rate constant of a reaction in terms of the partition functions of
The Eyring equation is particularly useful for analyzing the temperature dependence of reaction rates and for
