What Are the Van der Waals Constants for Sulfur Hexafluoride (SF6)?

Click For Summary
SUMMARY

The van der Waals constants for Sulfur Hexafluoride (SF6) are definitively established as follows: a = 6.871 L² bar/mol², b = 0.0562 L/mol, critical temperature (Tc) = 318.7 K, and critical pressure (Pc) = 37.6 bar. These constants are essential for accurately drawing the critical point and critical isotherm for SF6 in laboratory settings. They describe the intermolecular forces between SF6 molecules and are integral to the van der Waals equation, which models gas behavior under varying pressure and temperature conditions.

PREREQUISITES
  • Understanding of van der Waals equation

Could anyone here say me what's the constants of van der waals for the Sulfur Hexaflouride (SF6)
 
Physics news on Phys.org
please anyone can help me? it is so urgent since this is for draw the critical point and the critical isothermal for the laboratory. Or you can say me what's the critical molar volume or the critical volume for this gas, because I have the critical pressure and temperature.
 


The van der Waals constants for Sulfur Hexafluoride (SF6) are as follows:

a = 6.871 L^2 bar/mol^2
b = 0.0562 L/mol
Tc = 318.7 K
Pc = 37.6 bar

These constants describe the intermolecular forces between SF6 molecules, and are used in the van der Waals equation to calculate the behavior of gases at high pressures and low temperatures.
