(K), *10−5 (Pa), and *105 (m3/mole) are the critical temperature, pressure, and volume, respectively; *1010 (m) is the atomic (molecular) radius; *105 (m3/mole) is the free critical volume; *10−5 and *10−5 (Pa/K) are the experimental and calculated derivatives, respectively; (%) is the relative error.
