Complete and balance equation chart for formation of sulphuric acid.

PYRITE BURNER:

${\mathrm{FeS}}_2 + {\mathrm{O}}_2 \to \mathrm{\_\_\_\_\_} + \mathrm{\_\_\_\_\_}$

CONTACT TOWER:

${\mathrm{SO}}_2 + {\mathrm{O}}_2 \underset{{\mathrm{V}}_2{\mathrm{O}}_5/{\mathrm{K}}_2\mathrm{O}}{\overset{450°\mathrm{C}}{\to }} \mathrm{\_\_\_\_\_}$

ABSORPTION TOWER:

${\mathrm{SO}}_3 + {\mathrm{H}}_2{\mathrm{SO}}_4 \to \mathrm{\_\_\_\_\_}$

DILUTION TANK:

${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_{7 }+ {\mathrm{H}}_2\mathrm{O} \to \mathrm{\_\_\_\_\_}$

Why ${\mathrm{SO}}_3$ formed is not absorbed directly in water?

Why vanadium pentoxide is considered as a better catalyst than platinised asbestos?
