Importance of arrhenius equation

WitrynaThe Arrhenius equation is k = Ae^ (-Ea/RT), where A is the frequency or pre-exponential factor and e^ (-Ea/RT) represents the fraction of collisions that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea) at temperature T. 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 ...
