MCQ
The catalyst used in making $\mathrm{H}_2 \mathrm{SO}_4$​ in contact process is:
  • $ \mathrm{V}_2 \mathrm{O}_5 $
  • B
    $ \mathrm{Fe}_2 \mathrm{O}_3 $
  • C
    $ \mathrm{Cr}_2 \mathrm{O}_3 $
  • D
    $ \mathrm{CrO}_3 $​

Answer

Correct option: A.
$ \mathrm{V}_2 \mathrm{O}_5 $
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction. However, as it is susceptible to reacting.
