Definition

difference of initial amount $n_{B in}$ of substance $B$ (amount of substance) and equilibrium amount $n_{B eq}$ of substance $B$ (amount of substance) divided by stoichiometric number $ν_{B}$ of substance $B$ (stoichiometric number of substance):

ξ = \frac{n_{B eq} - n_{B in}}{ν_{B}}

quotient de la différence entre la quantité de matière $n_{B in}$ in initiale du constituant $B$ (amount of substance) et la quantité de matière $n_{B eq}$ du constituant $B$ (amount of substance) à l'équilibre par le nombre stœchiométrique $ν_{B}$ du constituant $B$ (stoichiometric number of substance):

ξ = \frac{n_{B eq} - n_{B in}}{ν_{B}}
