In preparation of sulphuric acid from sulphur dioxide in lead chamber process.What substance is used as a catalyst?

  • A. Manganese dioxide
  • B. Vanadium pentoxide
  • C. Nitric oxide
  • D. Raney Nickel

Step-by-step solution

In the lead chamber process for sulfuric acid production, sulfur dioxide is oxidized to sulfur trioxide using nitrogen oxides as catalysts. Nitric oxide (NO) acts as the catalyst, being oxidized to nitrogen dioxide (NO2) which then oxidizes SO2 to SO3, and is regenerated. Vanadium pentoxide is used in the Contact process, not the lead chamber process.
