Design a distillation column that can separate a mixture consisting of 40% acetone, 30% methanol, and 30% ethanol with a feed rate of 100 mol/h. The distillate should consist of at least 98% acetone, and the bottom product should contain no more than 1% acetone. You may assume that the column operates at a constant pressure and has 20 equilibrium stages. Determine the reflux ratio and the number of trays required to achieve this separation.

Calculate the enthalpy change of isomerization for the conversion of cis-2-butene to trans-2-butene, given that the heat of combustion of cis-2-butene is -3283.1 kJ/mol and the heat of combustion of trans-2-butene is -3336.8 kJ/mol. Assume that the heat of combustion is representative of the enthalpy of formation.
