Laboratory Studies on the Reactions between Chlorine, Sulfur Dioxide, and Oxygen: Implications for the Venus Stratosphere 1
نویسندگان
چکیده
The title reaction was studied by photolyzing mixtures of CI2 and SO2 with and without 02 present in an atmosphere of N2, using Fourier transform infrared spectrophotometry to monitor reactants and products. In the absence of oxygen, sulfur dioxide is quantitatively converted to sulfuryl chloride. With 10 to 150 Torr 02 present H2SO4 is produced as well as SO2C12. When a number of speculative reactions inferred from these experiments are added to a published model for Venus stratospheric chemistry, it emerges that SO2C12 is a key reservoir species for chlorine and that the reaction between CI and SO2 provides an important cycle for destroying 02 and converting SO2 to H2SO4. The modified model could provide a possible solution to the photochemistry of the Venus stratosphere if the mixing ratio of chlorine on Venus were as high as 8 ppm.

The photochemistry of the stratosphere of Venus was modeled using an updated and expanded chemical scheme, combined with the results of recent observations and laboratory studies. We examined three models, with H2 mixing ratio equal to 2 x 10 3, 5 x 10t, and I x 103, respectively. All models satisfactorily account for the observations of CO, 02, 0 2 CA), and SO2 in the stratosphere, but only th...
متن کاملCatalytic processes in the atmospheres of Earth and venus.
Photochemical processes in planetary atmospheres are strongly influenced by catalytic effects of minor constituents. Catalytic cycles in the atmospheres of Earth and Venus are closely related. For example, chlorine oxides (CIOx) act as catalysts in the two atmospheres. On Earth, they serve to convert odd oxygen (atomic oxygen and ozone) to molecular oxygen. On Venus they have a similar effect, ...
متن کاملAtmospheric Composition, Chemistry, and Clouds
Venus’ atmosphere has a rich chemistry involving interactions among sulfur, chlorine, nitrogen, hydrogen, and oxygen radicals. The chemical regimes in the atmosphere range from ion-neutral reactions in the ionosphere to photochemistry in the middle atmosphere to thermal equilibrium chemistry and surface-atmosphere reactions in the lower atmosphere. This variety makes Venus an important planet t...
متن کاملChemical composition of Venus atmosphere and clouds: Some unsolved problems
In spite of many spacecrafts that visited Venus, chemical composition of the Venus atmosphere and clouds present many challenging problems in observation and theory. The following problems are briefly discussed below: (1) molecular oxygen above the clouds, (2) lightning, (3) the blue absorption in the clouds, (4) mode 3 particle controversy and the Vega X-ray fluorescent observations, (5) searc...
متن کاملSulfur dioxide: episodic injection shows evidence for active venus volcanism.
Pioneer Venus ultraviolet spectra from the first 5 years of operation show a decline (by more than a factor of 10) in sulfur dioxide abundance at the cloud tops and in the amount of submicron haze above the clouds. At the time of the Pioneer Venus encounter, the values for both parameters greatly exceeded earlier upper limits. However, Venus had a similar appearance in the late 1950's, implying...
