WebHere, P is the gas pressure, V is the molar volume, T is the temperature, and R is the gas constant. To obtain a more realistic EOS, van der Waals introduced corrections that account for the ﬁnite volumes of the molecules and for the attractive forces (van der Waals forces) they exert upon each other at sufﬁciently small distances. WebExpert Answer. For carbon dioxide gas (CO2), the constants in the van der Waals equation are a = 0.364 J·mº/molº and b= 4.27 x 10-5 m3 /mol. The derivation of the ideal gas law employs two assumptions that are invalid for real gas molecules. First, the equation assumes that the molecules of the gas have no volume, which is not true for real ...
