Arrhenius Equation

[J Medina 2I]

What is ln [A] in the Arrhenius equation, ln kr = ln A - (Ea/RT)

[Sydney Myers 4I]

That equation is simply derived from a different one where the activation energy and gas constant and etc are all to the power of e. In order to make it a linear equation, it can be transformed into the one that you have typed. A is just the pre-exponential factor, its a constant.

[Sukanya Mohapatra 2G]

A is the pre-exponential factor. According to collision theory, A is the frequency of collisions in the correct orientation.

[DLee_1L]

Yeah, so A should be a decimal with 1 indicating that every collision results in a correct orientation and 0 indicating every time there is a collision, it is not in the correct orientation
