Answer 2

C) Assertion is correct but the reason is incorrect.

Sulphur burns in air, in the presence of oxygen, to form Sulphur dioxide which has a very pungent and suffocating odour. The reaction is as follows:

S     +       O₂    →     SO₂

Sulphur trioxide is formed when sulphur dioxide reacts with water. The reaction is as follows:

SO₂    + 1/2  O₂      →       SO₃

Hence, the reason statement is wrong.

Sulphur trioxide on reaction with water forms sulphuric acid. The reactions is as follows:

SO₃       +        H₂O         →         H₂SO₄  

Therefore, the assertion is correct and the reason is wrong.
