Atmosphere sulfur dioxide reaction with oxygen

The sulfur dioxide in Venus atmosphere is turned into sulfuric acid by two different chemical reactions. In the first reaction, the sulfur dioxide reacts with oxygen to form sulfur trioxide ... 

Most of the releases of carbonyl sulfide to the environment are to air, where it is believed to have a long residence time. The half-life of carbonyl sulfide in the atmosphere is estimated to be 2 years. It may be degraded in the atmosphere via a reaction with photochemically produced hydroxyl radicals or oxygen, direct photolysis, and other unknown processes related to the sulfur cycle. Sulfur dioxide, a greenhouse gas, is ultimately produced from these reactions. Carbonyl sulfide is relatively unreactive in the troposphere, but direct photolysis may occur in the stratosphere. Also, plants and soil microorganisms have been reported to remove carbonyl sulfide directly from the atmosphere. Plants are not expected to store carbonyl sulfide. 

The soils on Mt. Erebus were first described by Ugolini (1967). The rocks around the Main Crater of Mt. Erebus are coated with salts which also occur locally within the regolith. Keys (1980) and Keys and Williams (1981) identified the compounds listed in Table 16.3 which contain not only chlorine and fluorine, but also sulfate that forms by a reaction of sulfur dioxide gas with water vapor and oxygen of the atmosphere. In addition, the salts on the summit of Mt. Erebus contain aluminum, silicon, and iron (Keys and Williams 1981). Although some of the salt deposits in Eig. 16.22a and b are distinctly yellow, native sulfur is not present. Instead, the yellow deposits are probably composed of jarosite[(K,Na)(Ee,Al)(SO,),(OH)g]. 

Reaction (19) requires the reaction of oxygen from air and sulfur dioxide. What volume of air, at 500°C and one atmosphere pressure, is needed to react with the 1.00 X HP liters of SO2 produced from 50.8 kilograms of sulfur ... 

Chemical radicals—such as hydroxyl, peroxyhydroxyl, and various alkyl and aryl species—have either been observed in laboratory studies or have been postulated as photochemical reaction intermediates. Atmospheric photochemical reactions also result in the formation of finely divided suspended particles (secondary aerosols), which create atmospheric haze. Their chemical content is enriched with sulfates (from sulfur dioxide), nitrates (from nitrogen dioxide, nitric oxide, and peroxyacylnitrates), ammonium (from ammonia), chloride (from sea salt), water, and oxygenated, sulfiirated, and nitrated organic compounds (from chemical combination of ozone and oxygen with hydrocarbon, sulfur oxide, and nitrogen oxide fragments). ... 

Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Acidic deposition, or acid ram, as it is commonly known, occurs when emissions of sulfur dioxide (SO ) and oxides of nitrogen (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. This mixture forms a mild solution of sulfuric acid and nitric acid. Sunlight increases the rate of most of these reactions. 

Sulfides are converted to the oxide of the metal and sulfur dioxide by reaction with atmospheric oxygen ... 

Sulfur trioxide gas, one of the causes of acid rain, is produced in the upper atmosphere when oxygen reacts with sulfur dioxide gas in the reaction shown below ... 

The reaction of sulfur dioxide with oxygen in the atmosphere to form sulfur trioxide has important environmental implications because SO3 combines with moisture to form sulfuric acid droplets, an important component of acid rain. The following results were collected for two experiments involving the reaction at 600 °C between gaseous sulfur dioxide and oxygen to form gaseous sulfur trioxide ...
