Extracted text: Te Natural gas is produced in a gas field |Component (K) (bar)| (Pa (m³/kmol)²) | (m³/kmol) outside of the City of Grande Prairie and is delivered through a pipeline to a sales point. At the sales point, the pressure in the pipeline is 5 MPa [Propane and the temperature is 20°C. The natural gas is composed of 85 mol% methane, 10 mol% ethane and 5 mol% propane. Selected properties of these components have been provided in the table above. Using the information provided, answer the questions below. a b 190.6 46 305.3 49 369.5 42.5 Methane Ethane 5.56x105 0.0638 8.78x10 0.0845 (b) Calculate the van der Waals parameters a (in Pa· () and b (in m3 for methane. kmol
