Question

The process used for the production of sulphuric acid :

• A. Lead chamber process
• B. Haber process
• C. Deacon process
• D. Solvay process

Answer 1

Answer:

A. Lead chamber process

Contact process

However, the Lead Chamber process is indeed a method used for the production of sulfuric acid, but it's an older method.

Lead Chamber process:

This process was used from the 18th century until the early 20th century. It involves the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) using nitric oxide (NO) as a catalyst in the presence of water.

Contact process:

This is the modern method used for the production of sulfuric acid. It involves the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) using vanadium pentoxide (V2O5) as a catalyst.
