Arrhenius Equation

Postby BenJohnson1H » Thu Mar 14, 2019 10:08 am

How does one calculate the frequency factor, A, in the Arrhenius equation?

I dont recall prof Lavelle explaining in class but I remember him saying in this class we will generally be using A=1.

A as the pre-exponential factor/measure of the rate at which molecules collide is one of the Arrhenius parameters (the other being activation energy), which means it can only be found through experiments. I'd assume that we would be given the value of A if needed to solve a problem involving the Arrhenius equation.

Hey Ben!
In lecture he said if it's not given to you to just assume that the value is 1
