1.6(b) 1.19(b) The critical constants of ethane are Pc= 48.20 atm, Vc = 148 cm 3 mol -1 , and Tc = 305.4K. Calculate the van der Waals parameters of the gas and estimate the radius of the molecules.Solution:b = 4*N A (4πr 3 /3)r =1.7 (b) Use the van der Waals parameters for hydrogen sulfide to calculate approximate values of (a)the Boyle temperature of the gas (a = 4.484 L 2 atm mol -1 , b = 0.0434 L mol -1 .Solution:1.8 (b) Suggest the pressure and temperature at which 1.0 mol of (a) H 2 S, (b) CO 2 (c) Ar will be instates that correspond to 1.0 mol N 2 at 1.0 atm and 25°C.Solution:
1.8(b) A certain gas obeys the van der Waals equation with a = 0.76 m 6 Pa mol -1 . Its volume is found tobe 4.00 * 10 -4 m 3 mol -1 at 288K and 4.0 MPa. From this infonnation calculate the van der Waalsconstant b. What is the compression factor for this gas at the prevailing temperature and pressure?Solution:1.9(b) The second virial coefficient of methane can be approximated by the empirical equationwhere a = -0.1993 bar -1 , b = 0.2002 bar -1 , and c= 1131 K 2 with 300K < T < 600K . What is the Boyletemperature of methane?Solution:1.10 (b) The second virial coefficient B' can be obtained £Tom measurements of the density p of a gasat a series of pressures. Show that the graph of p/ρ against p should be a straight line with sloperoportional to B'.Solution:1.11(b) The equation of state of a certain gas is given by P =RT/V m + (a + bT)/V 2 m , where a and b are V constants.
