Note: using Microsoft excel for solution Computer applications in Chemical Engineering HW # 2 1.4 Problem Statement The ideal gas law can represent the pressure-volume-temperature (PVT) relationship of gases only at low (near atmospheric) pressures. For higher pressures more complex equations of state should be used. The calculation of the molar volume and the compressibility factor using complex equations of state typically requires a numerical solution when the pressure and temperature are specified. The van der Waals equation of state is given by (P+ )(V- b)- where (1) ) (2) and RT be SP (3) The variables are defined by P-pressure in atm V-molar volume in liters/g-mol T = temperature in K R- gas constant (R=0.08206 atm'liter/g-mol-K) Te-critical temperature (405.5 K for ammonia) Pe-critical pressure (111.3 atm for ammonia) Pr =- P Pc (4) Find the missing values in the following table, knowing that T=300K: 1 PU V 10 1 4 10
