3.1 Collision Theory

3.1.1. Concentration and Collisions

LO: I understand how the concentration affects the rate of a reaction.

Page 2: 3.1 Collision Theory

Collision theory states that substances can only react with each other if:

(i) The particles collide with each other and(ii) The collision has enough energy.

The the concentration of acid, the the number of collisions.

The the number of collisions the the rate of reaction.

LO: I understand how the concentration affects the rate of a reaction.

3.1.2 Particle Size and Collisions

LO: I understand how the particle size affects the rate of a reaction

Page 4: 3.1 Collision Theory

Collisions can only take place on the of a solid.

The greater the surface area the the number of collisions.

The smaller the particle size the the surface area.

3.1.3 Temperature and Collisions

LO: I understand how the temperature affects the rate of a reaction.

Page 6: 3.1 Collision Theory

Increasing the temperature makes the particles:

The greater the temperature the the rate of the reaction.

• move and collide more often

LO: I understand how the temperature affects the rate of a reaction

• collide with more .

In general, the rate doubles for every increase in temperature.
