Preferred Label : extent of reaction;
Detailed label : extent of reaction, ξ;
IUPAC definition : extensive quantity describing the progress of a chemical reaction equal to the number
of chemical transformations, as indicated by the reaction equation on a molecular
scale, divided by the Avogadro constant (it is essentially the amount of chemical
transformations). The change in the extent of reaction is given by dξ dnB/νB, where
νB is the stoichiometric number of any reaction entity strong B /strong (reactant
or product) and dnB is the corresponding amount.;
