Description:

The mass accommodation coefficient of SO2 and H2o2 on aqueos surfaces over the temperature range 260 - 292oK are reported. he experimental method used combined a monodisperse train of droplets and a low pressure flow reactor. ptake rates were determined by measuring changes in trace gas number density as a function of exposed liquid surface area. Results for SO2 showed an accommodation coefficient of 0.11 + 0.02 with no significant temperature variation. H2O2 showed a strong temperature dependence with an accommodation coefficient of 0.18 + 0.02.
