Which gas is used in the contact process?
A vanadium pentoxide catalyst is used in order to speed up the reaction
Why it is called contact process?
The contact process is named for the method by which sulfur dioxide (SO₂) is converted into sulfur trioxide (SO₃) through contact with a catalyst, typically vanadium(V) oxide (V₂O₅). This process involves the direct interaction or "contact" of the reactants in the presence of heat and the catalyst under controlled conditions. The efficiency and speed of this process, compared to earlier methods, led to its adoption in industrial sulfuric acid production, hence the name.
Name four Industrial catalysts and their uses?
Iron catalysts are used in the Haber process for ammonia synthesis. Platinum catalysts are used in catalytic converters to convert harmful gases into less harmful ones. Vanadium pentoxide is a catalyst used in the production of sulfuric acid. Nickel catalysts are used in the hydrogenation of vegetable oils to produce margarine.
Why is contact important in the disinfection process?
Contact is important in the disinfection process because it allows the disinfectant to come into direct contact with the pathogens present on a surface, ensuring that they are effectively killed or removed. Without sufficient contact time, the disinfectant may not be able to fully eliminate the pathogens, reducing the effectiveness of the disinfection process.
When water leaves the surfaces of plants to enter the atosphere what is the best and most specific term that is applied to describe this process?
evaporation
What are the optimum conditions for synthesis of sulphuric acid by contact process?
pressure- 1.5 to 1.7atms temp -400 to 450 celcius catalyst must be vanadium pentoxide or platinised asbestos
Which Catalyst used in manufacture of sulphuric acid?
Vanadium pentoxide (V2O5) is commonly used as a catalyst in the manufacture of sulfuric acid by the contact process. It helps to speed up the reaction of sulfur dioxide with oxygen to produce sulfur trioxide, which is then converted into sulfuric acid.
Which gas is used in the contact process?
A vanadium pentoxide catalyst is used in order to speed up the reaction
Where is sulfuric acid from?
Industrially sulfuric acid is made by the "contact process"- see wikipedia. This involves burning sulfur in oxygen to produce SO2 then oxidising further with O2 in the presence of a catalyst (vanadium pentoxide) to for SO3, then dissolving in water.
What are the observations when you heat ammonium metavanadate in a nickel crucible?
When heated, ammonium metavanadate decomposes to form vanadium pentoxide and water vapor. The yellow color of the vanadium pentoxide is observed during the heating process. The water vapor produced can condense on the cooler parts of the crucible.
What reaction produces sulfuric acid?
Sulfuric acid is commonly produced through the contact process, which involves the oxidation of sulfur dioxide to sulfur trioxide in the presence of a vanadium pentoxide catalyst. The sulfur trioxide is then hydrated to form sulfuric acid.
Which Catalyst used in manufacture of sulfuric acid?
Vanadium pentoxide (V2O5) is a commonly used catalyst in the manufacture of sulfuric acid via the Contact Process. It helps to speed up the reaction between sulfur dioxide and oxygen to produce sulfur trioxide, which is then dissolved in water to form sulfuric acid.
Why is a catalyst needed in the manufacture of sulphuric acid?
A catalyst is needed in the manufacture of sulfuric acid to increase the rate of the reaction without being consumed itself. The catalyst provides an alternative pathway with lower activation energy, allowing the reaction to occur faster at a lower temperature, thus saving energy and cost in the production process.
Why is it called contact process for preparation of sulphuric acid?
It is called the contact process because sulfur dioxide gas is brought into contact with a catalyst (usually vanadium oxide) in order to convert it to sulfur trioxide. This sulfur trioxide is then reacted with water to produce sulfuric acid. The name signifies the importance of the catalyst in facilitating the reaction.

What are the top three vanadium producing countries?
The top three vanadium producing countries are China, Russia, and South Africa. These countries have significant vanadium reserves and actively mine and process vanadium ores to produce the metal.
How sulphur di oxide converts into sulphur tri oxide?
Sulfur dioxide can convert into sulfur trioxide through a catalyzed reaction with oxygen. This reaction usually takes place in the presence of a catalyst such as vanadium pentoxide, at high temperatures. The process involves the oxidation of sulfur dioxide to form sulfur trioxide.
