Why do all chemical reactions conserve energy?

Why does a chemical reaction, such as setting off a firework, have a faster reaction rate?

The temperature of the particles is very high, so the particles are moving quicker than normal. 

The temperature of the particles is very low, so the particles are moving slower than normal.

Fireworks are very loud.

The temperature of the particles is the same as the outside air, so the particles naturally explode.
