A binary distillation column is operating under the conditions: feed rate 200 kmol/hr, bottom product rate 150 kmol/hr. mole fraction of the more volatile in the distillate is 0.95 and the bottom product is 0.05. x_{d} = 0.95, x_{w} = 0.05 reflux ratio is 2.5. in the stripping section, it is found that the mole fraction of the vapor leaving the plate is 0.35 while mole fraction of the liquid coming to the same plate is 0.20. find the mole fraction of the more volatile in the feed and also the type of feed.

Please show all the procedures.
