Question
These systems are modeled by a virial equation of state, which introduces non-vanishing higher-order terms like B. For 10 points each:
[10m] Name these systems that are modeled by cubic equations of state like the Redlich–Kwong equation. These systems are characterized by the compressibility factor deviating from one.
ANSWER: real gases [accept non-ideal gases; prompt on gases; reject “ideal gases”]
[10e] This equation of state models real gases by introducing a and b parameters representing intermolecular forces and particle size. This equation of state is named for the Dutch scientist who also names a type of intermolecular force.
ANSWER: van der Waals equation of state
[10h] Calculations for real gases replace partial pressure with this quantity, the pressure of an ideal gas with the same Gibbs free energy. The chemical potential for a real gas adds a term of RT times the logarithm of this quantity.
ANSWER: fugacity [prompt on phi]
