Could you do this problem using excel?

[@abdulazizaltayyari2390]

Final eq ( Ki - 1) not ( 1- Ki ) I think

[@homelessguy4395]

if you apply through negative symbol outside the brackets 1-ki becomes ki-1

[@southy2984]

Where do you get values for ki from?

[@VincentStevenson]

Ki in this example was made up, but it is the equilibrium constant for each species at VLE at a particular temperature and pressure that you look up from a table (thermodynamic property).

@@VincentStevenson Ki is the ratio of fugacity coefficient in the liquid phase to the fugacity coefficient in the vapor phase which can be calculated using EOS. Is this true ?

[@pelinalaca4739]

​@@VincentStevenson But that values are only available for light hydrocarbons. what about others? like benzene??
