Question

Using the information in the table, what are the compressibility factors for each temperature and density and for each equation of state. At which temperature and density does each of your gases behave most like a perfect gas? At which temperature and density dot's each of your gases behave least like a perfect gas? Using the NIST equation of state, plot the compressibility factor as a function of reduced pressure (i.e., P_r = P / P_c) for each of your systems at each reduced temperature on the same graph. Your graph should range from a reduced pressure of 0.2 to that of 5.0 with maximum steps of 0.2. Use for your atomic gas. for the diatomic gas, for the molecular gas in the graph. A style guide for the graph will be posted (30% of the grade on this problem will come from following the style guide). Critical and triple point information for each atomic and molecular system assigned. In the table below, T_t is the triple point temperature: T_c, P_c, pc are the critical point temperature, pressure and density, respectively; the accentric factor is required for the use of the Peng-Robinson equation of state. We should note that D_2O is also known as heavy water, CF_4, is R14 (Refrigerant 14), CHF_3 is R_23 (Refrigerant 23), CH_2F_2 is R32 (Refrigerant 32). and CH_3F is R41 (Refrigerant 41).
