Definition

for gases, product for all substances $B$ of partial pressure $p_{B}$ of substance $B$ (partial pressure) in power of its stoichiometric number $ν_{B}$ (stoichiometric number of substance):

K_{p} = Π_{B} {(p_{B})}^{ν_{B}}

pour les gaz, produit pour tous les constituants $B$ de la pression partielle $p_{B}$ du constituant $B$ (partial pressure) à la puissance $ν_{B}$ où $ν_{B}$ est son nombre stœchiométrique (stoichiometric number of substance):

K_{p} = Π_{B} {(p_{B})}^{ν_{B}}
