effect of temperature on rate

What is the activation energy

The minimum amount of energy that particles must have in order to react (collide successfully)

What does the size of the arrow on a particle in a diagram show

The energy of each particle

What happens if two particles with a low energy collide

They cannot overcome the activation energy barrier, so they wouldn’t collide successfully and no reaction would occur

What happens if two particles with a large amount of energy collide

They have enough energy to overcome the activation energy barrier and collide successfully, so a reaction takes place

What happens if you increase the temperature to the rate of reaction

Increases the rate of chemical reactions

How does increasing temperature increase the rate of reaftion

Increasing the temperature increases the energy of the particles. Because the particles now have more energy, they move faster, which increases the frequency of collisions

What is another way increasing temperature increases the rate of reaction

Increasing the temperature increases the energy of each collision. This means more particles can overcome the activation energy barrier and collide successfully
