Advancement

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 [MU∙s-1], e.g., ampere for electric flow or current [A≡C∙s-1], watt for heat flow [W≡J∙s-1], and for chemical flow the unit is [mol∙s-1]. The corresponding isomorphic forces are the partial exergy (Gibbs energy) changes per advancement [J∙MU-1], expressed in volt for electric force [V≡J∙C-1], dimensionless for thermal force, and for chemical force the unit is [J∙mol-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, νX, 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 νX. The advancement of the chemical reaction, drξ [mol], is then defined as

drξ = drnX·νX-1

The flow of the chemical reaction, Ir [mol·s-1], is advancement per time,

Ir = drξ·dt-1

Abbreviation: dtrξ
