Rearrangement Reaction: A reaction in which a reactant and product are isomers of each other. Chemical bonds within the reactant are broken and reformed to produce the product.

Redox Reaction: A reaction that involves transfer of electrons from one substance to another. Redox reactions always involve a change in oxidation number for at least two elements in the reactants.

Reaction Quotient: The product of the concentrations of the products, divided by the product of the concentrations of the reactants, for a chemical reaction which is not necessarily at equilibrium. For example . . . View Full Definition
