Topic 7 - Equilibrium

List four essential facts about systems in equilibrium.

* Its a closed system
* The forward and reverse reactions occur at the same rate
* There is not an equal amount reactants and products
* The concentrations of reactants and products do not change

Does adding a catalyst effect the position of equilibrium? Shift the equilibrium?

No.

What does it mean when the equilibrium constant is

* larger than 1
* smaller than 1
* equal to 1

* K >> 1 : products are favoured
* K << 1 : reactants are favoured
* K = 1 : neither are favoured

What is the only factor that changes the equilibrium constant K?

Temperature.

List three qualities of a closed system in dynamic equilibrium.

* Concentrations of reactants and products remain constant
* The rate of the forward and reverse reactions are equal
* The macroscopic properties remain the same
