Heterogeneous Decomposition of Ozone on Sulfuric Acid Surfaces at Stratospheric Temperatures.
Abstract
Methods of forming sulfuric acid aerosols at stratospheric temperatures were investigated, and the rate constant for the heterogeneous decomposition of ozone on sulfuric acid surfaces was determined over the temperature range 217 to 263K. The dependence of the decomposition rate constant on ozone concentration, relative humidity, and sulfuric acid surface area were studied and the data was interpreted in terms of the heterogeneous gas-surface kinetic model proposed by Judeikis and Siegel (1973). The role of heterogeneous reactions in the stratosphere is discussed, and recommendations for further experimental work are presented.
