Sulphuric acid is manufactured by the contact process.
Why H2SO4 is not obtained by directly reacting SO3 with water?

उत्तर
Sulphuric acid is not obtained directly by reacting SO3 with water because the reaction is highly exothermic, which produces the fine misty droplets of sulphuric acid that is not directly absorbed by water.
