Fugacity Examples 2: The Fugacity Of A “Hard-Sphere” Semi-Ideal Gas And The Van Der Waals Gas, Carl W. David
Fugacity Examples 2: The Fugacity Of A “Hard-Sphere” Semi-Ideal Gas And The Van Der Waals Gas, Carl W. David
Chemistry Education Materials
The fugacity of the van der Waals gas is obtained after a review of the concept itself.

Plotting The Van Der Waals Fluid In Pseudo-3d And The Maxwell Construction, Carl W. David
Plotting The Van Der Waals Fluid In Pseudo-3d And The Maxwell Construction, Carl W. David
Chemistry Education Materials
The van der Waals (from his thesis of 1873) equation is a cubic in the molar volume. Plotting the equation in pseudo 3 dimensions is quite simple to do, but including tie lines is quite difficult. Employing the solutions to the cubic van der Waals equation, the tie lines are readily available and can be easily incorporated into the aforementioned 3D plots.
Green Chemistry As A Tool For Understanding The Toxic Substances Control Act: A Lecture Module For Undergraduate Students, Molly R. Blessing
Green Chemistry As A Tool For Understanding The Toxic Substances Control Act: A Lecture Module For Undergraduate Students, Molly R. Blessing
Honors Scholar Theses
The Toxic Substances Control Act (TSCA) is the central form of chemical regulation existent in the United States today, yet scientists are often unaware or uncertain of its provisions. Violations of TSCA by unknowing chemists set industry and government unnecessarily at odds. A lecture on TSCA was developed for undergraduate students that uses the concept of green chemistry to promote interest and incentivize learning. Green chemistry methods are cleaner and less wasteful than traditional chemical ones, and many companies using them are at the forefront of technological innovation. The lecture explains both green chemistry and TSCA, includes company case studies, …
The Van Der Waals Equation As A Cubic, Carl W. David
The Van Der Waals Equation As A Cubic, Carl W. David
Chemistry Education Materials
The van der Waals (from his thesis of 1873) equation is a cubic in the molar volume. Since this is the first equation of state studied in chemistry more complicated than the ideal gas equation, it is noteworthy that the solution of this cubic is rarely if ever addressed. When (lowering the temperature) the two imaginary roots coalesce with the real root of the van der Waals equation we have the critical point. At Kelvin temperatures below Tc. the equation has three real roots; we explore obtaining those roots to aid in the Maxwell construction required to obtain the vapor …
