1. REVISION
EQUILIBRIUM

2. OPEN SYSTEM CLOSED SYSTEM REVERSIBLE REACTION CHEMICAL EQUILIBRIUM
continuously interacts with its environment,
CLOSED SYSTEM
is isolated from its surroundings.
REVERSIBLE REACTION
A reaction is reversible when products can be converted back to reactants.
CHEMICAL EQUILIBRIUM
It is a dynamic equilibrium when the rate of the forward reaction equals the rate of the reverse reaction

3. ONLY temperature can change this value!!!!
EQUILIBRIUM CONSTANT
No unit
ONLY temperature can change this value!!!!

4. EQUILIBRIUM CONSTANT – determine Kc

5. EQUILIBRIUM CONSTANT – determine Kc

6. EQUILIBRIUM CONSTANT – Kc given

9. EQUILIBRIUM IS DISTURBED BY…
Concentration
Temperature
Pressure
Volume

10. LE CHATELIER
When the equilibrium in a closed system is disturbed, the system will re-instate a new equilibrium by favouring the reaction that will oppose the disturbance
