Equilibrium
EQUILIBRIUM: Balance between two opposite processes happening at the same time.
Characteristics of Equilibrium Reactions:
1. Can only happen when the changes are REVERSIBLE.
2. Can only occur in a CLOSED SYSTEM where nothing is
allowed out.
3. The rate of the forward reaction equals the rate of the reverse
reaction.
4. The concentrations of the substances are constant (don’t change).
5. There’s a constant proportion between the reactants and products.
There are many Regents questions on this topic!
