Final answer:
When thermal energy is removed from a chemical reaction, the rate of reaction becomes slower.
Step-by-step explanation:
When thermal energy is removed from a chemical reaction, the rate of reaction usually becomes slower. This is because temperature is a measure of the kinetic energy of the particles involved in the reaction. When the thermal energy is removed, the particles have less energy to move and collide, resulting in fewer collisions and a slower rate of reaction.
