Question 2 of 2

What happens to the rate of a chemical reaction when the temperature increases?
The reaction rate increases because molecules move faster and collide more frequently with sufficient energy.
The reaction rate remains unchanged because temperature does not affect chemical reactions.
The reaction rate decreases because high temperatures break all chemical bonds, stopping the reaction.
The reaction rate decreases because higher temperatures slow down molecular movement.
