Define Le Chatlier's Priciple

When a change is made to a system in dynamic equilibrium, the position of the equilibrium shifts in the direction that minimises the effect of the change

1

What is a homogeneous equilibrium?

An equilibrium in which all the species making up the reactants and products are in the same physical state (You will only study this type of equilibrium)

2

What is a heterogeneous equilibrium?

An equilibrium in which species making up the reactants and products are in different physical states

3

What is the only factor that can change Kc

Temperature

4

What happens to the position of Kc and the yield of products for a endothermic reaction, when temperature increases

Kc increases and the product yield increases

5

What happens to the position of Kc and the yield of products for a exothermic reaction, when temperature increases

Kc decreases and yield of products decreases

6

State the effect of change in concentration on Kc

No change

7

State the effect of change in pressure on Kc

No change

8

State the effect of a catalyst on Kc

No effect

9

Define the equivalence point

The point in a titration at which the volume of one solution has reacted entirely with the volume of the second solution.
