2SO2 (g) + O2 (g) ----> 2SO3 (g)
The answer says that this reaction has the most negative change in entropy, and it's a multiple choice question, so we don't get values. But I thought the change in entropy was negative when it went from a solid to a liquid or gas.
What is the reason for this reaction having a negative change in entropy?

2 vol 1 vol 2 vol
As on the reactant side we have in total 3 vols. which becomes 2 vol. when the product is formed. Thus the the reactants are going to be organised when the product is formed. So the entropy is negative.
