3. Given the critical pressure, Pc, and the critical pressure, Tc, for CO2 are 73.75 bar and 304.13 K, respectively. (i) Assuming CO2 is an ideal gas, CALCULATE the critical volume, Vc. (ii) Assuming CO2 is a van der Waals gas, CALCULATE Vc. (iii) Assuming CO2 is a Redlich-Kwong, CALCULATE Vc. (iv) COMPARE the obtained Vc values in (i)–(iii) with that of the true Vc value; that is 0.09407 L.
