How can you tell the difference between a phase change and when a chemical reaction produces a gas?

A phase change should not, in general, require more than one compound. A chemical reaction, by definition, will involve at least two compounds. The only "exception" would be a decomposition reaction, but in that case two different compounds would be formed so it's not really an exception.
