Chapter 11, Problem 87AE

For the reaction

${\text{2N}}_{\text{2}}{\text{O}}_{\text{5}}\left(g\right)\to 4{\text{NO}}_2\left(g\right)+{\text{O}}_2\left(g\right)$

the following data were collected, where

$\text{Rate}\text{= }-\frac{\Delta \left[{\text{N}}_{\text{2}}{\text{O}}_{\text{5}}\right]}{\Delta t}$

Time (s)	T = 338 K [N2O5]	T=318K [N2O5]
0	1.00 × 10−1 M	1.00 × 10−1 M
100.	6.14 × 10−2 M	9.54 × 10−2 M
300	2.33 × 10−2 M	8.63 × 10−2 M
600.	5.41 × 1O−3 M	7.43 × 10−2 M
900.	1.26 × 1O−3 M	6.39 × 10−2 M
