Equilibrium

Definition

Equilibrium refers to the state in which both reactants and products are present in concentrations which have no further tendency to change over time. It's when forward and reverse reactions occur at equal rates so there's no net change observed.

Dynamic Equilibrium:

A state of balance between continuing processes.

Le Chatelier's Principle: This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

Equilibrium Constant (K):

The ratio of concentrations of products to reactants at equilibrium, each raised to a power equal to its stoichiometric coefficient in the balanced chemical equation.
