Question
Chapter 1, Problem 1.19NP
Interpretation Introduction
Interpretation:The pressure exerted by benzene for a molar volume of 2.00 L at 595 K with the help of Redlich-Kwong equation of state needs to be determined. Under these conditions, whether the attractive or repulsive portion of the potential dominant needs to be determined.
Concept Introduction: The ideal gas equation is the equation which gives the relations between P,V, n and T of gases. It can be written as:
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.
The Redlich-Kwong equation is represented as follows:
Here, a and b are constants.

Cylinders of compressed gas are typically filled to a pressure of 200 bar. For oxygen, what would be the molar volume at this pressure and 25 °C based on (i) the perfect gas equation, (ii) the van der Waals equation? For oxygen, a = 1.364 dm6 atm mol−2, b = 3.19 × 10–2 dm3 mol−1.
The Dieterici equation of state is similar to the van der Waals equation in that they both employ gas-specific constants a and b to attempt to account for the interaction between molecules and the nonzero volume of the individual molecules of gas. However, the Dieterici equation of state has a significantly different functional form:
?(? − ?) = ??? -a ⁄ (RVT)
Note that a and b are constants (n is implicitly constant as volume is expressed as molar volume). What are the following partial derivatives for the Diererici equation of state?
a) (∂P/∂T)V
b) (∂V/∂P)T
At what pressure does the mean free path of argon at 25 °c become comparable to the diameter of a spherical vessel of volume 1.0 dm3 that contains it? Take σ = 0.36 nm2
