内容記述 | The redox reaction rate of sulfur oxides in vapor clouds is crucial for estimation of the residence time of the sulfuric acid aerosol generated by the Chicxulub impact. In this study, conducted are laser irradiation experiments in order to estimate the redox reaction rate of sulfur oxides in vapor clouds. Analyzed is the final SO2/SO3 ratio in vapor clouds of the sulfate composition using a quadruple mass spectrometer (QMS) and estimated are the quenching temperature and the effective reaction rate of the reaction from SO2 to SO3 under high-temperature conditions. The present results suggest that the reaction rate at lower temperatures is much larger than that calculated by the theoretical model by Ohno et al. [2004]. | |||||
