Importance of arrhenius equation
WitrynaSignificance of Arrhenius Equation. The Arrhenius equation states that the rate at which a chemical reaction occurs is directly proportional to the concentration of the … In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates. The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that the van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and reverse reactions. This equation has a vast and important application in determinin…
