Question

SO2 can be defined by the Van der Waals equation ( C and D only)  ( A and B have posted answers)
A=
Vc=.171 L/mol
Tc=428.91 K
Pc=78.20 bar

b= 34.93 bar

SO2 can be defined by the Van der Waals equation of state with constants a =
= 6.86 bar*L2/mol?
and b = 0.057 L/mol.
What are Pc, Tc, and Vc for the gas?
а.
b. What is the total pressure in bar for a 1.41M concentration of the gas at 298K. The gas
constant in terms of bar is given by R=0.08314 L*bar/(mol*K)
С.
Assume that SO2 acts as an ideal gas instead. Calculate the pressure under the same
conditions.
d. Compare the pressures from the VdW equation and the Ideal Gas equation to obtain a
value for the compression factor, Z.
