The given question asks us to match industrial processes with their respective catalysts. Below are the detailed explanations for each of the processes and their catalysts:
- A) Ostwald's process:
- The Ostwald process is a method for producing nitric acid from ammonia.
- In this process, Rhodium (Rh) is the catalyst. The process involves the oxidation of ammonia to form nitric oxide (NO), which is further oxidized to form nitrogen dioxide (NO\(_2\)), which is absorbed in water to produce nitric acid. Rhodium is preferred due to its high catalytic activity and resistance to high temperatures and corrosive conditions.
- Matching: A-III
- B) Lead Chamber process:
- The Lead Chamber process is used in the industrial production of sulfuric acid.
- This process involves the oxidation of sulfur dioxide (SO\(_2\)) in the presence of nitrogen oxides (NO). The catalyst in this process is Nitric Oxide (NO), which facilitates the oxidation of sulfur dioxide. Nitric oxide helps in the formation of nitrogen dioxide (NO\(_2\)), which reacts with sulfur dioxide to form sulfur trioxide (SO\(_3\)), a precursor to sulfuric acid.
- Matching: B-I
- C) Deacon's process:
- The Deacon process is used to produce chlorine gas from hydrochloric acid (HCl).
- The catalyst used in this process is Copper chloride (CuCl\(_2\)). In this process, hydrogen chloride (HCl) is oxidized by oxygen in the presence of CuCl\(_2\) at high temperatures to produce chlorine gas (Cl\(_2\)) and water.
- Matching: C-IV
D) Haber’s process:
The Haber process is a method for synthesizing ammonia from nitrogen and hydrogen gases.
The catalyst used in the Haber process is Iron (Fe). The iron catalyst facilitates the combination of nitrogen (N\(_2\)) and hydrogen (H\(_2\)) gases at high pressure and temperature to form ammonia (NH\(_3\)).
Matching: D-II
Thus, the correct matching of processes to catalysts is A-III, B-I, C-IV, D-II.
