Question

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

b= 34.93 bar

C=34.934

d= Z=1

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.
From your value of Z, are the attractive forces or the repulsive forces larger under these
е.
conditions.
f.
From your knowledge of the lewis structure of SO2, does your value of Z seem
appropriate? Why or why not?

Expert Solution
Step 1

Z>1  

Z is compressibilty factor  

In this case attractive force more  than  repulsive force 

Z<1 

In this case  attractive force  is less than repulsive force 

Z=1 

Attractive force is equal to Repulsive force 

e) From the Z value concluded that PVnRT=1 So attarctive force is equlas to repulsive force
