Equilibrium Constants Flashcards
A state in which the ratio of concentrations of reactants and products is constant.
Chemical Equilibrium
Algebraic equations that describe the concentration relationships among reactants and products at equilibrium.
Equilibrium-constant expressions
Le Châtelier’s Principle states that the position of an equilibrium always shifts in such a direction as to relieve a stress that is applied to the system.
A shift in the position of an equilibrium caused by adding one of the reactants or products to a system.
Mass-action effect
A branch of chemistry that concerns the flow of heat and energy in chemical reactions.
Chemical Thermodynamics
Equilibrium-constant expressions allow us to predict the direction and completeness of chemical reactions.
Kw is called the ion-product constant for water.
The solubility of an ionic precipitate decreases when a soluble compound containing some of the ions of the precipitate is added to the solution.
Common-ion effect
Partial dissociation occurs when a weak acid or a weak base is dissolved in water.
