Contact Process 2024

2. A compound produced by the catalytic oxidation of sulfur dioxide, which reacts with water to form sulfuric acid.
3. A highly corrosive, strong acid used in a wide range of industrial processes, including the manufacture of fertilizers, chemicals, and explosives.
6. A chemical reaction that releases heat. The formation of sulfur trioxide from sulfur dioxide and oxygen is an exothermic reaction.
8. The catalyst used in the Contact Process to accelerate the oxidation of sulfur dioxide to sulfur trioxide.
9. A colorless gas produced by burning sulfur or sulfide ores, and the primary raw material in the Contact Process.
10. A solution formed by mixing sulfur trioxide in sulfuric acid, used in the Contact Process for the final absorption step.
11. A calcium carbonate is added to neutralize acidic fume (known as flue gas of desulphurization)

1. A method used for the large-scale production of sulfuric acid, involving the oxidation of sulfur dioxide (SO₂) to sulfur trioxide (SO₃), followed by absorption in water.
4. A chemical process in which a substance loses electrons, often associated with the addition of oxygen. In the Contact Process, sulfur dioxide is oxidized to sulfur trioxide.
5. The state in a chemical reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
7. A substance that increases the rate of a chemical reaction without being consumed in the process. In the Contact Process, vanadium(V) oxide is used as ....
