A 5 litre pressure vessel contains 200g of propane. Using the Peng Robinson EOS

A 5 litre pressure vessel contains 200g of propane. Using the Peng Robinson EOS calculate the pressure in the vessel at 50oC. What state is the propane likely to be in? (Show the intermediate calculation values of abm and a(T))100 g of propane is removed from the cylinder and is replaced with 100 g of ethane. Recalculate the pressure of the vessel at 50oC. Assume all binary interaction coefficients are zero. (Show the intermediate calculation values of a(T)mix and bmix)Critical parameters and acentric values:Ethane:MW = 30.069Pc = 707.79 psiaTc = 32.27 oCw = 0.0986Propane:MW = 44.096Pc = 616.41 psiaTc = 96.67 oCw = 0.1524
