Question

Data for the decomposition of hydrogen peroxide at some settemperature T is include below. The rate law depends only on theconcentration of H2O2.
2 H2O2 ---> 2 H2O + O2
t (seconds) 0 60 120 180 240 360 420 600
[H2O2] (M) 0.882 0.697 0.566 0.458 0.372 0.236 0.188 0.094
What is the value of the rate constant, k?
a) 0.12 /s
b) 3.7 x 10-3 /s
c) 270 / s
d) - 3.7 x 10-3 /s
e) 0.12 M/s
