Web24 de abr. de 2024 · Activation energy is a blanket term that's used to quantify all of the kinetic energy that can come from different sources and in various energy forms. Temperature is a unit of measure for heat energy, and as such, temperature affects the ambient and above ambient kinetic environment of a reaction. Function Web14 de mar. de 2024 · Also, if the activation energy is higher, the dependence of the rate constant on temperature increases, meaning at higher temperatures the rate constant is most likely going to be higher. These are a couple of the relationships that can be understood from the Arrhenius equation in the textbook. Hope that helps!
