Find the solution

Use Thermo Library 4 In a steady state distillation column equimolar feed for benzene and toluene is fed. The feed is saturated liquid. The top concentration is 98 mole % benzene and the bottom is 98% toluene. Write The gas phase is ideal. Example Code: The gammas for equimolar mixture of heptane and benzene at T=60+275.15 is given using the following code: from thermo import * from thermo.unifac import * constants,properties=ChemicalConstantsPackage.from_Ids(['heptane', 'benzene']) GE=UNIFAC.from_subgroups(chemgroups=constants.UNIFAC_Dortmund_groups, T=60+273.15,xs=[0.5,0.5]) GE.gammas() The output is [1.084689940175454,1.1514980615145518] This is a list, where the first element is the gamma for heptane and the second one is for benzene
