Question

If sulfur dioxide and oxygen can be made into sulfur trioxide, what is the reverse reaction?

Answer 1

Answer:

In a reversible reaction, reactants are converted into products but products again react to form reactants.

Therefore the formation of sulfur trioxide is a reversible reaction. Because this reaction can go in a backward and forward direction.

So the reversible reaction of sulfur trioxide is:

            2SO3 ⇌ 2SO2 + O2

In a reversible reaction, sulfur trioxide decomposes into sulfur dioxide and oxygen respectively.

Answer 2

Explanation:

Sulfur Dioxide & Sulfur Trioxide Reaction: Conditions & Equilibrium ... Sulfur trioxide is the result of further oxidation of sulfur dioxide. This reaction can go backward or forward (it is a reversible reaction); so the sulfur dioxide can be oxidized into sulfur trioxide, or the sulfur trioxide can be reduced into sulfur dioxide.
