Final answer:
When thermal energy is removed from a chemical reaction, the temperature of the reaction decreases and the rate of reaction slows down.
Step-by-step explanation:
When thermal energy is removed from a chemical reaction, the temperature of the reaction decreases. This is because thermal energy is a form of kinetic energy that is transferred between particles during collisions. When thermal energy is removed, the particles have less energy and move at slower speeds, resulting in fewer collisions and a slower rate of reaction.
