Explain ozone decomposes into oxygen by first-order kinetics

Reference no: EM13221449

Ozone (O3) is produced in the laboratory from oxygen (O2) by means of an electric discharge. Once generated, ozone gradually decomposes into oxygen by first-order kinetics. The following data were obtained from a sample of freshly prepared ozone:

time (min) 0 10 20 30 40 50

[O3], mM 0.40 0.28 0.20 0.14 0.10 0.07

What is the rate constant for the decomposition of ozone under these conditions?

3.47 X 10-2 min-1

4.50 X 10-2 min-1

6.34 X 10-2 min-1

1.057 X 10-1 min-1

3.658 X 10-1 min-1
