Saturated-liquid feed, of F = 40 mollh, containing 50 mol% A and B is supplied continuously to the apparatus shown in Figure. The condensate from the condenser is split so that half of it is returned to the still pot.(a) If heat is supplied at such a rate that W = 30 mol/h and a = 2, as subsequently defined, what will be the composition of the overhead and the bottoms product?(b) If the operation is changed so that no condensate is returned to the still pot and W = 30 as before, what will be the composition of theproducts?
