Yes, this is a true statement.

Yes, temperature has an effect on the speed of the reaction. Also most chemical reactions create heat. I feel that it is not exactly correct to say that most chemical reaction create heat. That is true for exothermic reactions, which give off heat, but endothermic reactions absorb heat instead.
I suppose that "chemical reaction" hasn't not a true antonym.
no, it is before the reaction

It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
Yes
A chemical reaction normally does have a product, and that product in some cases would be a polymer, but it is not true that a chemical reaction is a product or a polymer. It is a specific chemical change.
