1. (20 points) Please answer the following questions. (2 points) with a. (8 points) The compressibility factor at a critical point (Zc) is the van der Waals (vdW) equation of state and (2 points) with the Peng- Robinson (PR) equation of state. Which equation of state is expected to be more accurate in terms of density prediction, PR or vdW? Write your selection (4 points): a. (3 points) One of the main differences between the van der Waals EOS and the Peng-Robinson EOS is that the Peng-Robinson EOS uses acentric factor in addition to critical pressure and temperature. True or false%;, b. (3 points) When the Peneloux volume shift parameter is applied to the Peng-Robinson EOS, it changes the vapor pressure predictions because the EOS is altered by the volume shift. True or false; b. (6 points) A certain volume of a one-component fluid is in a high pressure vessel at a given temperature. With decreasing pressure isothermally, the fluid volume increases. It goes through the phase transition from 1-phase liquid, to 2 phases, to 1-phase vapor with decreasing pressure. During this isothermal expansion process, is it true that the pressure is constant when there are two phases in the vessel? True or false; (3 points). 1.
