Describe the steps in the manufacture of sulphuric acid

Answer:


 * Step 1:Burning of sulphur S + O2 --> SO2


 * Step 2:Converting sulphur dioxide into sulphur trioxide  2SO2 + O2 <=> 2SO3


 * Step 3:Adding concentrated sulphuric acid to sulphur trioxide to form oily product known as oleum. SO3 + H2SO4 --> H2S2O7


 * Step 4:Adding a calculated amount of water to form sulphuric acid.  H2S2O7 + H2O --> 2H2SO4
