Consider the van der Waals equation of state. a. Express the van der Waals equation of state as a virial expansion in powers of 1/Vm and obtain expressions for B and C in terms of the parameters a and b. Use the Taylor series expansion (1-x)=1+x+x²+... b. Measurements on argon yield B=-21.7 cm³ mol"' and C=1200 cmº mol2 for the virial coefficients at 273 K. Use these data to determine the corresponding values for the van der Waals coefficients a and b. Compare your results to tabulated values.
