oxygen and argon. CO, gas is well-described by the van der Waals equation of state, with
parameters a = 5.96 X 10° atm cm°/mol* and b = 98.6 cm /mol. If o.30 moles of CO, fills a
volume of 2.5 X 10°cm³ at a pressure of 1.7 atm;
A. What is the temperature of this gas (using the van der Waals equation as stated)?
B. What temperature would you calculate if you assumed that this was an ideal gas?
C. What are the absolute and relative differences between your results from A and B?
D. What is a variable (excluding the parameters a and b) that could be changed, and how, in
order for this CO, gas to behave more like an ideal gas?
E. Use either or both of the provided van der Waals parameters to estimate the effective
radius of a CO, molecule.
