2) a) Virial equation of state of real gases is expressed as Z = (PV / nRT) = 1 + (nB / V) + (n2C / V2). Derive the second virial coefficient B and the relation expressing the 3. virial coefficient C depending on the constants a and b in the van der Waals equation. b) The volume of a gas conforming to the van der Waals equation at a certain temperature and pressure of 4.00 x 106 Pa is 4.00 x 10-4 m3 / mol. For this gas, calculate the first and second Virial coefficients since it is known as a = 0.76 m6 Pa mol-2 and b = 0.13 lt / mol.
