WebThe Arrhenius Equation describes the relationship between the reaction rate and temperature. ln(kr)= ln(A)− Ea RT l n ( k r) = l n ( A) − E a R T. Where. A A in units of time−1 t i m e − 1 (eg. s−1 s − 1,min−1 m i n − 1 …) is called the frequency factor or pre-exponential factor. It describes the frequency that molecules ... WebJul 17, 2024 · For more than a century the Arrhenius equation serves as a powerful and simple tool to predict the temperature dependence of chemical reaction rates (Arrhenius, 1889). This equation, named after physical chemist Svante Arrhenius, posits that the reaction rate (k) is the product of a pre-exponential factor A and an exponential term that … black police association march in bristol
