2. Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
3. Exothermic Reactions
Endothermic Reaction Exothermic Reaction
The energy is absorbed from the surround into the reaction The energy is released from the system to its environment.
Energy in the form of heat Energy is released as heat, electricity, light or sound
4. The manufacturing temperature for making sulfur trioxide is 400-450o C.
5. A vanadium (V) oxide i.e (V 2 O 5 ) catalyst is used in the contact process
6. According to Le Chatelier's Principle, if you increase the pressure the system will respond by favouring the reaction which produces fewer molecules. ... In order to get as much sulphur trioxide as possible in the equilibrium mixture, you need as high a pressure as possible.
7. SO3 dissolution in water is extremely exothermic. This forces the sulfuric acid to form a mist of tiny droplets. These are highly corrosive which can even attack and corrode the lead pipelines and linings which cover the tower in contact process. Also, this mist does not condense so easily.
8. The major use of sulfuric acid is in the production of fertilizers, e.g., superphosphate of lime and ammonium sulfate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs.
