1B Pure butanol is to be fed into a semibatch reactor containing pure ethyl acetate to produce butyl acetate and ethanol. The reaction CH3COOC2H5+C4H9OHCH3COOC4H9+C2H5OH is elementary and reversible. The reaction is carried out isothermally at 300K. At this temperature, the equilibrium constant is 1.08 and the specific reaction rate is 9105dm3/mols. Initially, there is 200dm3 of ethyl acetate in the vat, and butanol is fed at a volumetric rate of 0.05dm3/s. The feed and initial concentrations of butanol and ethyl acetate are 10.93mol/dm3 and 7.72mol/dm3, respectively. (a) Plot and analyze the equilibrium conversion of ethyl acetate as a function of time. (b) Plot and analyze the conversion of ethyl acetate, the rate of reaction, and the concentration of butanol as a function of time. (c) Rework part (b), assuming that ethanol evaporates (reactive distillation) as soon as it forms
