... those compositions. For example, if M moles of a mixture with overall compositions, z i1 , are mixed with N moles of mixture with compositions, z i2 , the overall composition of the resulting mixture ... therefore, from Eq. 3.4.8 that K-values are also functions of composition. For example, equilibrium K-values for a phase diagram that includes a critical point must be strong functi...
