Chemical Equilibrium Glossary

State where forward and reverse reaction rates are equal and concentrations remain constant.

Reduction in solubility caused by addition of a common ion to solution.

Equilibrium where forward and reverse reactions continue at equal rates.

Ratio of product to reactant molar concentrations at equilibrium, each raised to stoichiometric powers.

The set of equilibrium concentrations; shifts with conditions but K only changes with T.

Equilibrium involving reactants and products in different phases.

Initial-Change-Equilibrium table used to organize equilibrium calculations.

Equilibrium constant expressed in terms of partial pressures of gaseous species.

Equilibrium constant for dissolution of a sparingly soluble ionic compound.

System at equilibrium shifts to counteract an applied stress.

Moles of solute dissolved per liter of saturated solution.

Expression identical to K but using current (non-equilibrium) concentrations.
