Pure S is burned with 20% excess air based on conversion to SO, 30% of the sulfur forms SO₃, the remainder forms SO₂,

a) What is the analysis of the burner gases?
b) The burner gas is passed through a converter. If the gases leaving the coverter have a mole fraction of 0.043 free O₂, what is the ratio of SO₃, to SO₂, in them.

c) What amount of sulfuric acid is produced if 30% of sulfuric acid is supplied in stoichiometric amount to the S03 produced.
