dcterms:description |
The equilibrium constant of a gas-phase reaction expressed on a pressure basis, \(K_p\): the product of the equilibrium partial pressures raised to their stoichiometric numbers, with each partial pressure referred to the standard pressure so that the quantity is dimensionless. This dimensionless convention follows the ISO 80000 / IEC 61360 vocabularies. The ECLASS vocabulary models the same concept dimensionally, with partial pressures in absolute units — that form is maintained separately as quantitykind:EquilibriumConstantBasedOnPressure, because the two dimension conventions cannot be reconciled by a fixed conversion factor. |
