The formulator of this equation rewrote it in terms of reduced variables to obtain the law of corresponding states.
More refined alternates to this equation include the Beattie-Bridgman and Benedict-Webb-Rubin equations. The formulator of this equation rewrote it in terms of reduced variables to obtain the law of corresponding states. Dependency on Pitzer's acentric factor was introduced to a modification of this equation by Soave. Another modification of this equation is used in the petroleum industry because it performs slightly better at the critical point than the Redlich-Kwong equation. That is the Peng-Robinson equation. This equation incorrectly predicts a critical compressibility factor of three-eighths. This equation uses constants a and b to correct for intermolecular forces and finite molecular size, respectively. For ten points, name this modification of the ideal gas law created by a Dutch scientist.
