Now, if this was not an elementary reaction, we would not be able to use this A and B the way we did here. Now for now, we're only going to worry about elementary reactions. So this is our rate law. Now this KF, our rate constant depends strictly on temperature and types of reactants. It does not depend on the concentrations of reactants nor products. Now, we saw from another video that KF is known as the Iranians equation and it depends strictly on temperature.
