CHEMICAL EQUILIBRIUM
KEY POINTS:
1. Common ion effect:
The decrease in the solubility of an electrolyte in a solution in the presence of a common ion is called the common ion effect.
2. Equilibrium constant:
The equilibrium constant is the ratio of forward rate constant (kf) and backward constant (Kr) for a reaction at a given condition.
3. Law of mass action:
The rate at which a substance reacts is proportional to its active mass and the rate of a chemical reaction is proportional to the product of the active masses of the reacting substances.
4. Le-Chatelier's principle:
If a system at equilibrium is disturbed, it behaves in such a way as to nullify the effect of that substance.
