Description
Advancement per volume or volume-specific advancement, dtrY, is particularly introduced for chemical reactions, drY, where it has the dimension of a concentration. In an open system at steady-state, however, the concentration does not change as the reaction advances. Only in closed systems, specific advancement is the change in concentration divided by the stoichiometric number, ΞrY = Ξci/Ξ½i. In general, Ξci is replaced by the partial change of concentration, Ξrci, which contributes to the total change of concentration, Ξci. In open systems at steady-state, Ξrci is compensated by the external contributions, Ξextci, to the total concentration change, Ξci = Ξrci + Ξextci = 0.
