Description
In an isomorphic analysis, any form of flow is the advancement of a process per unit of time, expressed in a specific motive unit [MUās-1], e.g., ampere for electric flow or current [Aā”Cās-1], watt for heat flow [Wā”Jās-1], and for chemical flow the unit is [molās-1]. The corresponding isomorphic forces are the partial exergy (Gibbs energy) changes per advancement [JāMU-1], expressed in volt for electric force [Vā”JāC-1], dimensionless for thermal force, and for chemical force the unit is [Jāmol-1], which deserves a specific acronym ([Jol]) comparable to volt. For chemical processes of reaction and diffusion, the advancement is the amount of motive substance [mol]. The concept was originally introduced by De Donder. Central to the concept of advancement is the stoichiometric number, Ī½X, associated with each motive component X (transformant [1]).
In a chemical reaction, r, the motive entity is the stoichiometric amount of reactant, drnX, with stoichiometric number Ī½X. The advancement of the chemical reaction, drĪ¾ [mol], is then defined as
drĪ¾ = drnXĀ·Ī½X-1
The flow of the chemical reaction, Ir [molĀ·s-1], is advancement per time,
Ir = drĪ¾Ā·dt-1
Abbreviation: dtrĪ¾
