Key Concepts

Chemical Equilibrium

This concept refers to the state in a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, even though both reactions continue to occur. It is a dynamic balance rather than a static condition.

Equilibrium Constant (Kc)

The equilibrium constant, expressed as Kc when concentrations are involved, quantifies the ratio of the concentrations of products to reactants at equilibrium. Depending on its value, Kc provides insight into whether the equilibrium mixture is product-favored or reactant-favored, and it is specific to a given reaction at a specific temperature.

Reaction Quotient (Q)

The reaction quotient, Q, is calculated using the same expression as the equilibrium constant but with the current concentrations of the reactants and products. By comparing Q to Kc, one can determine the direction in which a reaction must proceed to reach equilibrium; if Q is less than Kc, the reaction will shift toward products, and vice versa.

Le Chatelier's Principle

This principle states that if a system at equilibrium experiences a change in concentration, pressure, temperature, or volume, it will adjust in a way that partially counteracts the imposed change. This helps predict the direction in which the reaction will shift in order to re-establish equilibrium.
