Question
Use the information about three gases, with the properties below to answer the following questions. Nitrogen (N2) Oxygen (02) Argon (Ar) 93.0 °C 83.0 °C 73.0 °C M (kg/kmol) 28 32 40 Use the van der Waals equation of state and mixing rules to calculate the temperature where 100 kmol of a mixture of argon (10 mol%), nitrogen (45 mol%) and oxygen (45 mol %) would occupy 46.27 m³, at a pressure of 6.28 MPa. It is known that the van der Waals constant for nitrogen are a=1.370 atm(m³/kmol)² and b=0.0387 m³/kmol, and for oxygen are a=1.382 atm(m³/kmol)² and b=0.03186 m³/kmol. 63.0 °C Tc (K) 126.2 154.6 150.8 Pc (atm) 33.5 49.8 48 @ 0.04 0.021 -0.004
