States of Matter & Gas LawsKinetic Molecular Theory
The model that explains gas behaviour in terms of large numbers of tiny particles in constant random motion.
Chemical Bonding & Molecular StructureOdd-Electron Molecule
A species containing an unpaired electron, so that its total electron count is odd and no octet structure is possible.
Chemical Kinetics & CatalysisTermolecular Reaction
An elementary step requiring the simultaneous collision of three species.
Chemical Kinetics & CatalysisUnimolecular Reaction
An elementary step in which a single molecule rearranges or decomposes.
Chemical Kinetics & CatalysisActive Site
The specific region of a catalyst or enzyme at which the reacting molecules bind and are transformed.
Stoichiometry & Chemical ReactionsAddition Reaction
A reaction in which two molecules combine to form a single larger product, with no atoms left over.
