The partial molar volume of a component in a mixture depends on properties of the component
and of the mixture. List these properties and relevant equations and outline how partial molar
volumes can be determined experimentally.
a. Give a thermodynamic interpretation of the terms break and halt
b. Sketch an example of a phase diagram for a binary mixture of compounds A and B, which are solids at room temperature. The melting point of A is higher than that of B. The eutectic point is at 80 mol %A. Compound AB melts incongruently.
