The reason behind the stoppage of the liquid–vapor boundary line in the phase diagram of a substance at a certain point is to be explained. Concept introduction: A phase diagram is a graph that represents the solid, liquid, and gaseous phases of a substance at different pressures and temperatures. The lines are the boundaries between the two phases and represent the conditions under which the two phases are in equilibrium.

6.The diagram below is an example of Liquid-Vapor(LV) Pressure (P vs Mole Fraction).Fill out the question marks with correct number of degrees of freedom. LV Pressure – Composition (LV – PZ) Phase Diagram | How to read this phase diagram: XA = 0 Xe = 1 P = Pg Xx = 1 • We can designate the fraction of A and B in the liquid be XA and Xa, while the fraction of A and B in the gas phase be ya and Yg- XB = 0 F=? Liquid Phase F=? • Z, is the composition of A: • Below the vapor curve, or the bubble curve, A is pure vapor, and Z, = VA • Above the liquid curve, or the dew curve, A is pure liquid, and Z, = Xa P P= P F=? Vapor Phase YA = 1 YA = 0 Ya = 1 ZA Ys = 0

Chemistry The vapor pressure, P, of a certain liquid was measured at two different temperatures, T. The data is shown in this table. T (K) P (torr) 293.6 145.3 356.9 783.5 If you were going to graphically determine the enthalpy of vaporization, AHmp, for this liquid, what points would you plot? To avoid rounding errors, use three significant figures in the x values and four significant figures in the y values. point 1: x = point 1: y = point 2: x = point 2: y = Determine the rise, run, and slope of the line formed by these points. rise: run: slope: What is the enthalpy of vaporization for this liquid?
