Terms in this set (12)

  • Chemical Equilibria
    A state where the concentrations of reactants and products remain constant over time in a reversible reaction.
  • Equilibrium Constant
    A value expressing the ratio of product to reactant concentrations at equilibrium for a reversible reaction.
  • Thermodynamics
    A field focusing on the direction and energy changes of chemical reactions, especially at equilibrium.
  • Chemical Kinetics
    A branch of chemistry concerned with the speed at which reactants are converted into products.
  • Le Chatelier's Principle
    A rule predicting how a system at equilibrium responds to disturbances by shifting to minimize the effect.
  • Equilibrium State
    A condition where the forward and reverse reaction rates are equal, resulting in no net change in composition.
  • Reactants
    Substances initially present in a chemical reaction that undergo change to form products.
  • Products
    Substances formed as a result of a chemical reaction from the transformation of reactants.
  • Disturbance
    Any change in conditions, such as concentration or temperature, that affects a system at equilibrium.
  • Reaction Shift
    A movement of a chemical reaction toward more products or reactants to counteract a disturbance.
  • Direction
    The tendency of a chemical reaction to proceed toward either more products or more reactants.
  • Reversible Reaction
    A process where reactants can form products and products can revert to reactants under certain conditions.
