Here is an Overview of Equilibrium and Key Take Aways to remember:
Kinetic Molecular Theory says: All substances are made up of particles that are in constant motion and sometimes collide/interact.</p>
- When particles have Effective collisions (EC), particles (reactants) rearrange into new groupings (products) and we say there is a chemical reaction (rxn).
Question: THEN WHAT?
- Two possibilities:
- Irreversible rxn :
- Reversible rxn:
- Forward reaction:
- Backward or reverse reaction:
Virtually All Chemical Reactions are ____________________
- Big condition needed for a reaction to be reversible: Closed system -

Definition of Equilibrium:
- Big Take Aways for Equilibrium:
- ? What happens if you disturb Equilibrium?
LeChatelier's Principle says:
If a stress is applied to an equilibrium system, the system will "try to remove the stress to get back to the original system/conditions.
- Big Take Away: Can't get there (changed system), so create new one
- Big Take Away: System can only make forward rxn go more or backward go more to remove stress to make new equilibrium.
- LeChatelier's Principle would say stress would:
- Equilibrium shifts to Left - More reactant in new equilibrium compared to original equilibrium
- Equilibrium shifts to Right - More products in new equilibrium compared to original equilibrium</p>
- Not affect equilibrium</p>
