A mixture of carbon-toluene tetrachloride with 40% molar composition. Both components must be separated with a purity 95% molar in a continuous rectification column, determine:

a.The number of minimum dishes

b.La minimum reflux ratio, if the feed enters liquid form at boiling temperature

c.The number of dishes required to carry out the indicated separation, if a reflux ratio 35% higher than the minimum is used, with the average efficiency of the column being 70%

d.La amount of distilled product per kmol/kmol of feed.
