Is the differential rate law derived from experimental data?

Is the differential rate law derived from experimental data? Meaning, did chemists just do chemical reactions enough times and manipulated data enough times that they found combinations of terms that seemed meaningful in some way?

OR is there some way to truly derive the differential rate law?

By performing experiments using the method of initial rates, scientists can get a good guess of what the rate law is (the orders of each reactant). Then, a mechanism is proposed to explain this rate law. More advanced experiments can confirm whether or not this mechanism is correct!

A lot of it was experimental because the k value is experimentally determined for a certain temperature.
