Decreasing the particle size increases the reaction rate because

• It makes particles move faster
• It increases the likelihood of collisions with the correct geometry
• It decreases the surface area available to react
• It increases the number of collisions

Why does a higher temperature increase the rate of a reaction?

• it increases both the frequency and energy of particle collisions
• it only increases the frequency of particle collisions
• it only increases the energy of particle collisions
• it reduces the activation energy of the reaction
