Question
Chapter 2, Problem 2.37P
Interpretation Introduction
(a)
Interpretation:
The value of vapor pressure at T = 185 °C should be determined by using two-point linear interpolation.
Concept introduction:

Interpretation Introduction
(b)
Interpretation:
The vapor pressure at 148.2 °C and the percentage error considering given value should be determined along with the reason for expecting the error which is associated with part (a) to be significantly less than part (b).

4. In the phase diagram of pure ammonia, NH3, the solid-liquid coexistence line can be
expressed as
P = 69.1-T – 13503 solid-liquid coexistence line
|
and the liquid-vapor coexistence line can be expressed as
P = 7.642x10-4.T² – 0.3183-T+ 33.4
liquid-vapor coexistence line
where pressures are given in units of atm and temperatures are in units of K.
The triple point of the ammonia phase diagram has a temperature of
a. Tự = 197.2 K
b. Tự = 195.4K
c. Tự = 410.6 K
d. Tự is indeterminate
Comelli and Francesconi examined mixtures of propionic acid with various other organic liquids at 313.15 K (F. Comelli and R. Francesconi, J. Chem. Eng. Data 41, 101 (1996)). They report the excess volume of mixing propionic acid with tetrahydropyran (THP, oxane) as VE = x1x2{a0 + a1(x1 − x2)}, where x1 is the mole fraction of propionic acid, x2 that of THP, a0 = −2.4697 cm3 mol−1, and a1 = 0.0608 cm3 mol−1. The density of propionic acid at this temperature is 0.971 74 g cm−3; that of THP is 0.863 98 g cm−3. (a) Derive an expression for the partial molar volume of each component at this temperature. (b) Compute the partial molar volume for each component in an equimolar mixture.
