. 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.
