## Homework Statement

The rate of the reaction was studied at a certain temperature.

O(g) + NO2(g) --> NO(g) + O2(g)

In the first set of experiments, NO2 was in large excess, at a concentration of 1.0 * 10^ 13 molecules/cm3 with the following data collected.

time (s) [O] (atoms/cm3)

0 ......2400

0.01.....1200

0.02.....600

0.03......0

Part (a). Find the reaction order with respect to O. (Explain with graphs)

Part (b) Find the rate constant with respect to O.

## Homework Equations

Rate = K[A]

First Order Reaction Integrated Rate Law: ln[A] = -kt + ln[A]0

## The Attempt at a Solution

I want to know how to transform the graph/data set into a linear line to find the reaction order (I think it is first order). I think I ln[O] and plot it against time (s) to achieve a linear graph for a first order graph. How do I do that? Do I need to convert atoms/cm3 to mol/L? I tried doing that and it is not looking right. Help would be appreciated!
