And this is exactly what we get from experiments some constant k which we can say they're equal times the concentration of this guy squared times the concentration of BR two. This is exactly what we get from experiments. And so our rate laws do coincide. Now, once again, whenever our rate law is not the first step, it's the second or third step. We have to take into consideration the intermediate guys because the intermediate guys will determine the concentration of reactants for the slow step. And that's why they need to be taken into consideration.
