(a) If one of the roots of this equation is V= 183.7 cm'/mol, confirm if this is Vi for the liquid phase or gas phase, giving your reasoning. (b) Using the data in part (a), calculate the residual molar volume V" (cm'/mol) and compressibility factor Z, for NF, at 300K and 97 bar. Give your answers to 2 decimal places. (c) Estimate the compressibility factor, Z, using an appropriate correlation for the second virial coefficient. Hence, confirm whether or not the SRK is a good model for NF, at 300K and 97 bar. Tc = 234K, PC = 44.6 bar and w- 0.126.
