Chapter 11, Problem 37E

The decomposition of hydrogen peroxide was studied, and the following data were obtained at a particular temperature:

Time(s)	[H2O2](mol/L)
0	1.00
120 ± 1	0.91
300 ± 1	0.78
600 ± 1	0.59
1200 ± 1	0.37
1800 ± 1	0.22
2400 ± 1	0.13
3000 ± 1	0.082
3600 ± 1	0.050

Assuming that

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

determine the rate law, the integrated rate law, and the value of the rate constant. Calculate [H₂O₂] at 4000. s after the start of the reaction.
