Sulfuric acid (H2SO4) is prepared commercially from elemental sulfur using the contact process. In a typical sequence of reactions, the sulfur is first burned:
S + O2 --> SO2 ,
then it is converted to SO3 using a catalyst:
2 SO2 + O2 --> 2 SO3
The resulting SO3 is reacted with water to produce the desired product:
SO3 + H2O --> H2SO4
How much sulfuric acid could be prepared from 65 moles of sulfur?
