This equation contains factors which account for the volume of individual molecules as well as the attractive forces between molecules, its b and a terms.
One graphical representation of this equation exhibits spurious loops which imply that certain substances have negative compressibility. That region is modified by a horizontal line determined by the Maxwell equal area rule. A later modification of this equation introduced a T to the one half term in the denominator of the A parameter; that equation was introduced by Redlich and Kwong. This equation contains factors which account for the volume of individual molecules as well as the attractive forces between molecules, its b and a terms. For 10 points, identify this equation of state, the first modification of the ideal gas law to describe real gases, which was developed by a Dutch scientist.
