The kinetic classification of complexes according to how rapidly they exchange their ligands.
Chemical Kinetics & CatalysisLangmuir Adsorption Isotherm
A model describing monolayer adsorption on a surface with a fixed number of equivalent, independent sites.
States of Matter & Gas LawsLatent Heat
The energy absorbed or released when a substance changes state, with no accompanying change in temperature.
Chemical Bonding & Molecular StructureLattice Energy
The energy released when one mole of an ionic solid is formed from its constituent gaseous ions.
Foundations of ChemistryLaw of Conservation of Mass
The principle that the total mass of the substances in a closed system is unchanged by any chemical reaction.
Foundations of ChemistryLaw of Definite Proportions
The principle that a given chemical compound always contains its constituent elements in the same fixed mass ratio.
Chemical EquilibriumLaw of Mass Action
The principle that the rate of a reaction is proportional to the product of the active masses of the reactants.
Foundations of ChemistryLaw of Multiple Proportions
The principle that when two elements form more than one compound, the masses of one element combining with a fixed mass of the other are in…
Nuclear & RadiochemistryLaw of Radioactive Decay
The principle that the rate of decay is proportional to the number of undecayed nuclei present.
Stoichiometry & Chemical ReactionsLaw of Reciprocal Proportions
The principle that the mass ratios in which two elements combine with a third are related by a simple ratio to the ratio in which they…
Chemical EquilibriumLe Chatelier's Principle
When a system at equilibrium is disturbed, it responds in the direction that partially opposes the disturbance.
Inorganic & Coordination ChemistryLeaching
The selective dissolution of a metal or its compound from an ore using a suitable chemical reagent.
Electrochemistry & RedoxLead–Acid Accumulator
A rechargeable cell using lead and lead dioxide electrodes in sulfuric acid.
Acids, Bases & SaltsLevelling Effect
The tendency of a solvent to reduce all acids or bases stronger than its own ionised forms to the same effective strength.
Chemical Bonding & Molecular StructureLewis Structure
A diagram showing the bonding and lone pairs of a molecule using dots or lines for valence electrons.
Acids, Bases & SaltsLewis Theory
The theory defining an acid as an electron pair acceptor and a base as an electron pair donor.
Inorganic & Coordination ChemistryLigand
An ion or molecule that donates one or more electron pairs to a central metal atom.
Inorganic & Coordination ChemistryLigand Field Theory
The refined bonding model that combines crystal field theory with molecular orbital treatment of metal–ligand covalency.
Solutions & Colligative PropertiesLike Dissolves Like
The empirical rule that substances dissolve best in solvents with similar polarity and bonding character.

Electrochemistry & RedoxLimiting Molar Conductivity
The molar conductivity of an electrolyte extrapolated to infinite dilution, where ionic interactions vanish.
Stoichiometry & Chemical ReactionsLimiting Reagent
The reactant that is completely consumed first and therefore determines the maximum amount of product obtainable.
Chemical Bonding & Molecular StructureLinear Geometry
A molecular shape in which the bonded atoms lie on a straight line, giving a bond angle of 180°.
