@E02281@ 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 @A00543@ (it is essentially the @A00297@ of chemical transformations). The change in the extent of reaction is given by \(\mathrm{d}\xi =\frac{\mathrm{d}n_{\text{B}}}{\nu _{\text{B}}}\), where \(\nu _{\text{B}}\) is the @S06025@ of any reaction entity B (reactant or product) and \(\mathrm{d}n_{\text{B}}\) is the corresponding amount.
