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
