Plots of natural log of k vs 1 over the temperature can be used to figure out the activation energy of the system from the slope.
Unlike the theoretical Eyring one, this model is empirical in nature. Plots of natural log of k vs 1 over the temperature can be used to figure out the activation energy of the system from the slope. A modified version of this compares the  current temperature of the system to a baseline temperature to show the independence of that activation energy to the  pre-exponential factor A, which represents the number of collisions that occur every second. FTP, provide this equation  named for a Swedish chemist and used to describe the effect of temperature on the rate constant of a reaction.
