Recognizing the Order of a Reaction

In the reaction 2 A + 2 B ----> C + 3 D the rate of disappearance of A is -2.2 X 10^-4 M s -1. What is the rate of formation of C?

The answer states A = to 1.1 x 10^-4 M/s.

What happened to the "-1" in this situation? Can these measures for rates, Ms^-1 and s-1, be used to help identify first second and third order?

When looking at these types of problems, what is the quickest way to recognize the order?

Solution Preview

There are two ways of writing the same thing, because x^-1 = 1/x. Look at that carefully to make sure you understand that.

Therefore, 1.1 x 10^-4 M/s is the same as 1.1 X 10^-4 M s^-1. Okay? So, no problem ...
