Chemical Equilibrium — 6 Terms Defined

Chemical Equilibrium Chemical Equilibrium Dimensionless The state of a reversible reaction in which the forward and reverse reactions proceed at equal rates, so no net change in composition occurs. aA + bB ⇌ cC + dD

Combining Equilibrium Constants Chemical Equilibrium Various The rule that when two reactions are added, their equilibrium constants multiply. K_overall = K₁ × K₂

Common Ion Effect Chemical Equilibrium mol/L The suppression of the ionisation or dissolution of a substance by adding a second substance that supplies one of the same ions.

Complex Ion Equilibrium Chemical Equilibrium mol/L The equilibrium between a metal ion, its ligands and the resulting complex ion in solution. M + nL ⇌ MLₙ

Concentration Equilibrium Constant Chemical Equilibrium Various The equilibrium constant expressed in terms of the molar concentrations of the species involved. Kc = [C]^c[D]^d / [A]^a[B]^b

Coupled Equilibria Chemical Equilibrium Dimensionless Two or more equilibria that share a common species, so that shifting one necessarily shifts the others.
