This equation can be derived from perturbation theory's hard sphere model.
This equation can be derived from perturbation theory's hard sphere model. One parameter is multiplied by the square of moles over volume and added to pressure in this equation, and a second parameter is multiplied by number of moles and subtracted from volume. Those parameters denoted, a and b, are this equation of state's namesake parameters. For 10 points, name this deviation from the ideal gas law, named after a Dutch scientist that also lends his name to weak intermolecular bonds.
