- If a binary mixture is an ideal solution with composition XA, and if the order parameter (in this case, composition) can be either non-conserved (allowing chemical reaction, for example), or conserved. At what composition would equilibrium be established and why, for each of the two cases?
Homework Answers
In case a mixture does not change composition in a process,then binary system can be treated as a pseudo single-component substance.
In the case of non-ideal solutions, it might not be possible to separate A and B

A solution contains 59.0 g of heptane (C7H16) and 44.5 g of octane (C8H18) at 25 ∘C. The vapor pressures of pure heptane and pure octane at 25 ∘C are 45.8 torr and 10.9 torr, respectively. Assuming ideal behavior, calculate each of the following. (Note that the mole fraction of an individual gas component in an ideal gas mixture can be expressed in terms of the component's partial pressure.) The vapor pressure of heptane in the mixture. The vapor pressure...
