Chapter 12, Problem 46E

The rate of the reaction

O ( g ) + NO 2 ( g ) NO ( g ) + O 2 ( g )

was studied at a certain temperature.

a. In one experiment, NO2 was in large excess, at a concentration of 1.0 × 1013 molecules/cm3 with the following data collected:

Time(s) [O](atoms/cm3)
0 5.0 × 109
1.0 × 10−2     1.9 × 109
2.0 × 10−2 6.8 × 108
3.0 × 10−2 2.5 × 108

What is the order of the reaction with respect to oxygen atoms?

b. The reaction is known to be first order with respect to NO2· Determine the overall rate law and the value of the rate constant.
