WebFor a real (non-ideal) gas (superscripted as rg in the following) species in a non-ideal gas mixture, we can write analogously, making use of our deﬁnition of fugacity as presented in the section on pure gases, as: µrg i (T,p) = µ rg i (T,p ref,pure) + RT ln fˆ i fref i! (15) Here, fˆ i is the fugacity of species in the non-ideal gas ... WebThe fugacity coefficient takes a value of unity when the substance behaves like an ideal gas. Therefore, the fugacity coefficient is also regarded as a measure of non-ideality; the closer the value of the fugacity coefficient is to unity, the closer we are to the ideal state. Fugacity turns out to be an auxiliary function to chemical potential. WebDec 31, 2015 · 1 Answer. In an ideal solution, the fugacity of a component in the mixture is equal to the fugacity of the pure component at the same temperature and pressure as the mixture times the mole fraction of the component in the mixture.
