Question

What happens to any chemical reaction when the temperature is increased?

• A. Its rate decreases
• B. Its rate increases
• C. It stops
• D. It goes at a slower rate

Answer 1

The correct option is B Its rate increases

When temperature increases, the kinetic energy of molecules increases. The molecules move around faster and collide with each other more often, thus increasing the probability of the reaction occurring. This increases the reaction rate.
