Collision Theory Intro

Aluminum (Al) can react with both chlorine (Cl₂) and fluorine (F₂) to make aluminum chloride (AlCl₃) and aluminum fluoride (AlF₃). Imagine we have a beaker where all the particles are moving with the same average amount of energy. Even though the particles have the same average energy, when aluminum bumps into fluorine molecules, reactions happen way more often than when it bumps into chlorine molecules.

Look at the picture and chart provided. How does what you see in the picture help explain why aluminum reacts more easily with fluorine than with chlorine?

In order for a chemical reaction to occur, the particles of the reactants must _________ .

(Be sure to write your answer down on your notesheet)

Will a chemical reaction occur every time particles collide with each other?

In order for a chemical reaction to occur,

Collisions must have enough ___________ ________ to break existing bonds & form new ones.

(Don't forget to write the answer on your notesheet)

The minimum energy needed for a collision to be successful is called the _______ _______.

In addition to having enough kinetic energy, particles also must have the correct ________ when they collide in order for a collision to be effective.

Note that in this reaction, the oxygen atom (orange) had to collide with a nitrogen atom (green) in order for the collision to result in a change. This is because the oxygen had to form a bond with one of the nitrogen atoms from the other molecule.

In your own words, explain what orientation means and why it is important for a reaction to occur.
