The unit compressibility line is analyzed at a nonzero pressure point of intersection with the inversion curve, assuming that the unit compressibility line is linear in the T-d plane. It is shown that this assumption requires both the inversion curve and an isotherm to have local zero slopes at the intersection point viewed in the compressibility factor vs. pressure plane, results not observed in Z, P representations of properties.
For the system considered above, it was found that R = 4, so that a maximum of three solid phases can occur at equilibrium. Thus, a t least two solid phases must vanish as the reaction proceeds. Unfortunately, the phase rule does not tell us which solid phases must vanish. This must be determined as the equilibrium calculation proceeds. However, the choice of which solid phases to remove from the calculation is not completely arbitrary. For example, in the reaction system considered above one would not attempt to remove both Fe and FeO. This unfortunate choice would drop the rank of the atomic matrix to 3 and would obviously wreak havoc with the requirement that atomic iron be conserved. Similarly, CaC03 and CaO would not be removed simultaneously, al-, l Y l -,.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
