Predicate	Object
`rdf:type`	`qudt:QuantityKind`
`dcterms:description`	The equilibrium constant of a reaction in solution expressed on a concentration basis, \(K_c\): the product of the equilibrium amount-of-substance concentrations raised to their stoichiometric numbers, with each concentration referred to its standard value 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 concentrations in absolute units — that form is maintained separately as quantitykind:EquilibriumConstantBasedOnConcentration, because the two dimension conventions cannot be reconciled by a fixed conversion factor.
