Ethene (C2H4) reacts with ozone (O3) to form ethene ozonide (C2H4O3):
O3+C2H4→C2H4O3
In a university laboratory experiment the rate of disappearance of ozone (O3) was measured to be 9 x 10-3 M/s. Simultaneously, the concentration of ozone was measured to be 9 x 10-5 M and the concentration of ethene 2.5 x 10-7 M. Given that this chemiluminescent chemical reaction follows the following rate law:
Rate=k[O3][C2H4]
