The Arrhenius equation states that the rate at which a chemical reaction occurs is directly proportional to the concentration of the … WitrynaIn 1889, a Swedish scientist named Svante Arrhenius proposed an equation that relates these concepts with the rate constant: where k represents the rate constant, Ea is the …
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 reactants raised to the power of the activation energy divided by the temperature. The equation is used to predict the rate of a chemical reaction at a given temperature. WitrynaThe Arrhenius equation (Arrhenius, 1889; see Chapter 1) for chemical kinetics was experimentally derived for aqueous solutions and electrolytic dissociation. It was known that the temperature T influences the reaction rate, expressed in terms of the so-called equilibrium rate constant κ = κ 1 / κ 2 representing the ratio between the ...
