Equilibirum Quick Summary Flashcards
The rate of reaction?
The rate of the forward reaction equals the rate of the reverse reaction.
The concentration of products is?
CONSTANT.
What is meant by La Chatelier’s Principle?
If a system is at equilibrium is subjected to any change, the system readjusts itself to counteract the applied change.
Add more reactant
Moves to right, more product
Add more product?
Moves to left, makes more reactant
Remove product?
Moves to right.
Remove reactant?
Moves to left
Increase temperature?
Moves in endothermic direction, Delta H positive
Decrease temperature?
Moves in exothermic direction, where Delta H is negative
Increase pressure?
Moves to side with least number of moles of gas
Decrease Pressure?
Move to side with most moles of gas.
Add a catalyst?
No effect on equilibrium position, just reaches equilibrium quicker!
