172 kmol/h of a liquid mixture of XBR and water enter through the top of a column containing a molar fraction ofXBR of 0.3155. The liquid mixture leaves the team containing a molar fraction of XBR of 0.0766. On the other hand, the gas used to carry out the separation (water vapor + XBR) has a molar fraction of0.0476 of XBR, since it comes from a recycling stage. The flow of gas to be used (Vs, in Kmol/h) must be 1.55 times the minimum.A. What are the values of X1, X1, X2, X2, Y1,11 & L2?
