a Review | Constants Periodic Table Part A The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k= Ae-E/RT where R is the gas constant (8.314 J/mol K). A is a constant called the frequency factor, and E is the activation energy for the reaction. The activation energy of a certain reaction is 47.9 kJ/mol. At 25 °C, the rate constant is 0.0190s . At what temperature...

Learning Goal: To use the Arrhenius equation to calculate the activation energy. As temperature rises, the average kinetic energy of molecules increases. In a chemical reaction, this means that a higher percentage of the molecules possess the required activation energy, and the reaction goes faster. This relationship is shown by the Arrhenius equation k=Ae−Ea/RT where k is the rate constant, A is the frequency factor, Ea is the activation energy, R = 8.3145 J/(K⋅mol) is the gas constant, and T...
