SO3 is not absorbed in water directly to form H2SO4 because:
Correct answer: C. The reaction is highly exothermic
- A. The reaction does not go to completion
- B. The reaction is quite slow
- C. The reaction is highly exothermic
- D. SO3 is insoluble in water
Explanation
SO3 dissolution in water is extremely exothermic. This forces the sulfuric acid to form a mist of tiny droplets. These are highly corrosive which can even attack and corrode the lead pipelines and linings which cover the tower in contact process. Also, this mist does not condense so easily.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
