Chapter 6, Problem 6.3P
Ethyl alcohol has a vapor pressure of 20.0 mm Hg at 8.0°C and a normal boiling point of 78.4°C. Estimate the vapor pressure at 45°C using (a) the Antoine equation: (b) the Clausius—Clapeyron equation and the two given data points; and (c) linear interpolation between the two given points.
Taking the first estimate to be correct, calculate the percentage error associated with the second and third estimates.

Fatty acid mixtures can be used as drug release systems by taking advantage of the different thermal properties of the mixture when compared to those of the pure substances. A mixture of two fatty acids, myristic acid (MA) + stearic acid (SA), exhibits the following (experimentally determined) phase diagram.
Sketch a cooling curve for 64% MA over the temperature range of 68 to 40 o Each time the slope of cooling curve changes, label the approximate temperature, as well as the components and phase (or phases) present in that region of the curve.
