Abstract
An apparatus has been designed and constructed which will rapidly mix two gaseous reactants, isolate them in a reaction cell, and, by means of light absorption, follow the course of the reaction photoelectrically in one-tenth of a second or less. The output of the photoelectric tube is recorded by a time-exposure photograph of the screen of an oscilloscope.The kinetics of the fast reaction between ozone and nitrogen dioxide was studied over a tenfold range of concentration of each reactant. The rate law was found to be [dformula -d(O[sub 3])/dt [equals sign] k(NO[sub 2])(O[sub 3])] over the entire course of the reaction. From the temperature coefficient of the rate of reaction the energy of activation was found to be 7.0±0.6 kilo-calories per mole. A mechanism is proposed to account for the observations.
