Boltzmann– arrhenius function
WebMay 18, 2024 · Boltzmann constant in Chemical kinetics Relationship with Arrhenius equation. Arrhenius equation is a very important equation in chemical kinetics. It associates the rate constant of a chemical reaction with temperature. The rate constant is a function of temperature and activation energy. WebJul 30, 2007 · However, the Boltzmann–Arrhenius function did not adequately represent the fall in growth rate; the decline in growth rate above 1100 m was greater than predicted. Perhaps the Boltzmann–Arrhenius …

The Arrhenius law predicts that the motion of the structural units (atoms, molecules, ions, etc.) should slow down at a slower rate through the glass transition than is experimentally observed. In other words, the structural units slow down at a faster rate than is predicted by the Arrhenius law.
