. The catalyst used in contact process is


A: Al2O3

B: Cr2O3

C: V2O5

D: MnO2

 

Best Answer

Explanation:

  • Contact process
  • By contact process, H2SO4(Sulphuric acid) is prepared in presence of V2O5(Vanadium oxide).                                           

 SO2 (g)+1/2O2 (g) SO3 (g)

 (Sulphur dioxide) (Oxygen) (Sulphur trioxide)                                                                                                                 

  • The catalyst in the above reaction is V2O5.

Final Answer:

Hence, Option (C) is correct.
