Using polymath:

Pure butanol is to be fed into a semibatch reactor containing pure ethyl acetate to produce butyl acetate and ethanol. The reaction CH3COOC2H5 + C4H,OH CH3COOC4H9 + C2H5OH is elementary and reversible. The reaction is carried out isothermally at 300 K. At this temperature the equilibrium constant is 1.08 and the specific reaction rate is 9x10-5 dm3/mol/s. Initially, there is 200 dmof ethyl acetate in the vat and butanol is fed at a rate of 0.05 dm3/s. The feed and initial concentrations of butanol and ethyl acetate are 10.93 mol/dm3 and 7.72 mol/dm3, respectively. (a) Plot the equilibrium conversion of ethyl acetate as a function of time. (b) Plot the conversion of ethyl acetate, the rate of reaction, and the concentration of butanol as a function of time
