1. A system has been designed and constructed which will mix two gaseous reactants, isolate them in a reaction cell, and follow the entire course of the reaction photoelectrically in one-tenth of a second. The output of the photoelectric tube is recorded by a time-exposure photograph of the screen of an oscilloscope.
2. The kinetics of the fast reaction between ozone and nitrogen dioxide mas studied over a ten-fold range of each reactant. The rate law was found to be [...] over the entire course of the reaction. As expected from the speed of the reaction, the energy of activation was found to be low, 6.4 kilocalories per mole. A simple two-step mechanism is proposed to account for the observations.
1. In an effort to obtain information about the mechanism of the formation of red phosphorus from white phosphorus in a solution of phosphorus tribromide, a radioactive tracer study was made of that system. Tentative explanations are advanced for certain features of the process.
2. A great variety of colors of polymerized phosphorus were observed in this study, and correlations between presumed size and color are discussed.
