Fractal and negative rate orders

I just mentioned that the order of a reaction can be any real number, even a negative one, but what does this actually mean  

In the previous example we determined the rate order to be m = 1.5. How can we interpret this result Let s assume, we have the following reaction  

We set the rate constant to 38 (for simplicity sake we do not worry about the units in this example, but you should work out the units of k for each rate order) and get the following data  

This graph shows that the rate for the reaction with m=1.5 is between the two other rates. There is nothing special about this particular rate order - it just says that at concentrations of A 1 unit (here mM) the rate for m= 1.5 is faster than the rate for m=l. 0 and slower than the rate for m=2.0. 

Negative rate orders indicate inhibition of a reaction
