Question

1.) Estimate the volume change of vaporization for ammonia at 20ºC. At this temperature, the vapor pressure of ammonia is 857 kPa.

2.) Consider o-xylene at 240ºC. Determine Z and V (cm3 /mol) when: a.) P = 1 bar (vapor) b.) P = 4 bar (vapor) c.) P = 7.43 bar (saturated vapor) d.) P = 7.43 bar (saturated liquid)

3.) Consider the o-xylene from Problem 2. What is the final volume of the liquid if the saturated liquid at 240ºC and 7.43 bar is cooled to 60ºC and compressed to a.) 20 bar, or b.) 50 bar? c.) Comparing the volumes in (a.) and (b.), is it safe to assume the liquid is incompressible? Given: b = 9.6 × 10, and k = 8.0 × 10)

4.) Treat chlorobenzene as a Redlich/Kwong gas at 506 K and 6 bar. Solve for the molar volume by iteration. Continue iterations until the value changes by less than 2%. Let a= 6.575 × 10^5 and B = 290.8 .

Selected Answers (within ±25%): 1.) 2500 cm3/mol 2.) V (in cm3 /mol) ~: a.) 40,000; b.) 10,000; c.) 5,000; d.) 200 3.) V ~ 150 cm3/mol 4.) V ~ 6500 cm3/mol
