WAS BEDEUTET FUGACITY AUF ENGLISCH
Fugacity
In der chemischen Thermodynamik ist die Fuge eines echten Gases ein wirksamer Druck, der den wahren mechanischen Druck in genauen chemischen Gleichgewichtsrechnungen ersetzt. Es ist gleich dem Druck eines idealen Gases, das das gleiche chemische Potential wie das reale Gas hat. Zum Beispiel, Stickstoffgas bei 0 ° C und ein Druck von hat eine Fuge von. Das bedeutet, dass das chemische Potential von echtem Stickstoff bei einem Druck von 100 atm geringer ist als wenn Stickstoff ein ideales Gas wäre; Der Wert des chemischen Potentials ist derjenige, der Stickstoff als ideales Gas bei einem Druck von 97,03 atm hat. Fugacities werden experimentell bestimmt oder aus verschiedenen Modellen wie einem Van-der-Waals-Gas, das der Realität näher als ein ideales Gas entspricht, Der ideale Gasdruck und die fugacity sind durch den dimensionslosen Fugacity-Koeffizienten verknüpft. Bei Stickstoff bei 100 atm beträgt der Fugazitätskoeffizient 97,03 atm / 100 atm = 0,9703. Für ein ideales Gas sind Fugalität und Druck gleich, so ist 1. Der Beitrag der Nonidealität zum chemischen Potential eines realen Gases ist gleich RT ln. Wieder für Stickstoff bei 100 atm ist das chemische Potential μ = μid + RT ln 0.
Definition von fugacity im Wörterbuch Englisch
Die Definition der Fugazität im Wörterbuch heißt auch: Entweichungsneigung eine Eigenschaft eines Gases, bezogen auf seinen Partialdruck, die seine Entweichungs- oder Expansionsneigung ausdrückt, gegeben durch d = dμ / RT, wobei μ das chemische Potential ist, R die Gaskonstante und T die thermodynamische Temperatur f. Andere Definition von Fugacity ist der Zustand oder die Eigenschaft, fugacious zu sein.

(3.5) The standard state fugacity is fg0i = 1atm. For an ideal gas mixture, fugacity
is the same as partial pressure, and fgi = Pi. Fugacity coefficient, χi = fgi/Pi,
indicates the degree of nonideality of the gas mixture. Note that Pi = yiPT, where
