What Do You Know About Arrhenius Equation?
(104).jpg "What Do You Know About Arrhenius Equation? - Quiz")
In the late 1880s, Nobel Prize-winning Swedish scientist Arrhenius proposed Arrhenius equation, which is a formula for the temperature dependence of reaction rates. Presently, it is an empirical relationship that can be used to model the temperature variation of diffusion coefficients, the population of crystal vacancies, creep rates, and many other thermally-induced processes and reactions.
