Definition

for solutions, product for all substances $B$ of concentration $c_{B}$ of substance $B$ (particle concentration) in power of its stoichiometric number $ν_{B}$ (stoichiometric number of substance):

K_{c} = Π_{B} {(c_{B})}^{ν_{B}}

pour les solutions, produit pour tous les constituants $B$ de la concentration $c_{B}$ en constituant $B$ (particle concentration) à la puissance $ν_{B}$ où $ν_{B}$ est son nombre stœchiométrique (stoichiometric number of substance):

K_{c} = Π_{B} {(c_{B})}^{ν_{B}}

Units

{(unitsml(mol/m^3))}^{\sum ν_{B}}

mole per cubic metre to the power of sum of stoichiometric numbers
