C8.2 Collision Theory

Question 1

What is the collision theory?

Answer 1

Reacting particles have to collide with one another and make a product - which is called a successful collision

Question 2

What is the activation energy?

Answer 2

Minimum amount of energy that particles must have before they react

Question 3

How are reactions more likely to happen?

Answer 3

Increase the frequency of reacting particles colliding with each other
Increase the energy they have when they collide

Question 4

How does surface area affect the rate of reaction?

Answer 4

Increasing the surface area of a substance in the chemical reaction increases the exposure of that material to the reactant.
This leads to an increase in the frequency of the collisions which then increases the rate of reaction
