Four hundred and fifty lbmol/h of a mixture of 60 mol% benzene (LK) and 40 mol% toluene (HK) is to be separated into a liquid distillate and a liquid bottom product of 95 mol% and 5 mol% benzene, respectively. The feed enters the column with a molar percent vaporization equal to the distillate-to-feed ratio. Use McCabe-Thiele method to compute, at 1 atm (101.3 kPa): (a) Nmin, (b) Rmin, (c) Number of equilibrium stages N, for R/Rmin = 1.3, (d) The optimum feed-stage location
