CIMS-flow reactor studies of the reaction SO3+H2O+M→H2SO4+M
Description
We studied the reaction SO3+H2O+M → H2SO4+M in a stainless steel flow tube reactor in the pressure range between 31 and 260 mbar. SO3 was produced within the flow reactor by the help of a radical source. The concentration of reactant SO3 as well as the concentration of the product H2SO4 was measured by Chemical Ionization Mass Spectrometry (CIMS). Rate constants in the range between 0.72 and 1.39 x 10-15 cm3s-1 were obtained. Averaging over the total pressure range of the experiments yields a mean value of 1.2 ± 0.2 x 10-15 cm3s-1. These values are considered to be due to gas phase reactions only. (author)
