Use both the van der Waals and the Redlich-Kwong equations to
calculate the molar volume of CO at 213 K and 1036 bar. (Take
a = 1.4734 dm6·bar·mol−2 and
b = 0.039523 dm3·mol−1 for the van
der Waals equation and A = 17.208
dm6·bar·mol−2·K1/2 and B
= 0.027394 dm3·mol−1 for the Redlich-Kwong
equation.)
Calculate the molar volume under the same conditions using the
ideal-gas equation.
Answer in dm3·mol−1.
