    Chemical Equilibrium

    Definition

    • Chemical equilibrium: a state where the rates of forward and reverse reactions are equal, and the concentrations of reactants and products remain constant.

    Characteristics

    • Equilibrium is a dynamic state, not a static one.
    • The reaction is still occurring, but at equal rates in both directions.
    • The equilibrium state is characterized by a constant ratio of concentrations of products to reactants.

    Equilibrium Constant (K)

    • A measure of the extent to which a reaction proceeds to completion.
    • Represented by the symbol K (or Keq).
    • Defined as the ratio of the concentrations of products to reactants at equilibrium.

    Types of Equilibrium Constants

    • Kc: equilibrium constant in terms of concentration (moles per liter).
    • Kp: equilibrium constant in terms of partial pressures.

    Factors Affecting Equilibrium

    • Concentration: increasing the concentration of reactants drives the reaction forward.
    • Temperature: increasing temperature can shift the equilibrium to the right (forward reaction) or left (reverse reaction).
    • Pressure: increasing pressure can shift the equilibrium to the right (forward reaction) or left (reverse reaction).

    Le Chatelier's Principle

    • When a system in equilibrium is subjected to a change in concentration, temperature, or pressure, the equilibrium will shift to counteract the change.
    • The system will respond to the change to re-establish equilibrium.

    Applications of Equilibrium

    • Industrial processes: optimizing reaction conditions to maximize yield and efficiency.
    • Biological systems: understanding the regulation of metabolic pathways.
    • Environmental systems: modeling the fate of pollutants in the environment.
