Now, my question is how do we determine the order of our reaction, namely A and our rate constant KF? Well, one way to do it, as we saw, is to determine using experimental results. So we find the initial concentrations and the initial rate and we use that information to determine their relationship or the relationship between A and our rate of our reaction. And using that this guy and our concentration, we can then find our KAP. Well, that's one way to do it. A second way to do it is with graphing.
