Any physical changes that change during a chemical reaction are the consequence of the products physical properties. The melting point may be much lower than the reactants and change state but ultimately it was the properties responsible for this and not the chemical reaction itself.
If anything there are situations where the two both occur somewhat simultaneously as well as situations where chemical change doesn't proceed with a physical change and vice versa.
