Answer 2

Answer:

This process is called Contact Process.

Explanation:

• In the contact process, we can produce sulphuric acid.
• We first extract sulfur from different ores and rocks found on earth.
• The sulfur extracted is burned in the excess air to produce sulfur dioxide, $SO_{2}$.
• The sulfur dioxide is oxidized too in presence of vanadium peroxide which acts as a catalyst. It is converted to sulfur trioxide.
• We need to add a diluted form of sulfur trioxide to sulphuric acid to produce oleum, $H_{2}S_{2}O _{7}$.
• Oleum is then diluted too to form sulphuric acid, $H_{2}SO_{4}$.
