Write an equation for the reaction of galena with oxygen to produce sulfur dioxide and lead(II) oxide.
Identify the oxidation number changes that occur during this reaction.
State the temperature normally selected for this conversion and explain it using reaction rates and Le Chatelier’s principle.
State and explain the pressure conditions that would produce the best rate and best yield of sulfur trioxide. Explain why these conditions are not actually used.
Explain why the sulfur trioxide is not dissolved directly in water to produce sulfuric acid.
Write equations for sulfur trioxide reacting with sulfuric acid and for the later reaction with water.
Explain why sulfur dioxide is added to certain foods and wines.
