15.3

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

15.3

Why don't we divide the average rate by the number of moles.

In this problem, when I found reaction rate of NO2, I got 0.0065 mole/Ls

Why wouldn't I divide or multiply that number by 2 based off the equation given of 2NO2 --> 2NO + O2?

Re: 15.3

The concentrations you are given are in terms of NO2 so there is no need to convert them as we are finding the rate of reaction in terms of NO2. You can see that in part b, you must use the coefficients to find the rate of formation of O2.

Re: 15.3

As someone already said, the units are already Moles of N02 L^-1S^-1 so you don't need to divide by moles of N02
