Design a distillation column for the separation of a binary mixture consisting of ethanol and water. The feed mixture contains 40 mol% ethanol and 60 mol% water, and the desired product purity is 95 mol% ethanol. The feed rate is 1000 kg/hr and the column should operate at atmospheric pressure. Calculate the number of theoretical plates required to achieve the desired separation and determine the corresponding height and diameter of the column.

Design a chemical reactor for the exothermic reaction A + B -> C, given the following parameters: - The reaction takes place at a temperature of 500°C- The reaction rate constant is 0.05 L/mol/min- The feed stream contains both A and B in equal molar amounts, with a total flow rate of 100 L/min- The desired product, C, should have a concentration of at least 90% in the reactor effluent stream- The reactor should have a residence time of at least 5 minutes. Determine the type of reactor (batch, plug flow, or continuously-stirred tank) and the dimensions (volume, length, diameter) required to achieve the desired product concentration and residence time, assuming an isothermal and well-mixed reactor.

Calculate the enthalpy change for the combustion of 1 mole of methane (CH4) gas given that the standard enthalpy of formation of methane is -74.8 kJ/mol, and the standard enthalpies of formation for carbon dioxide (CO2) and water (H2O) are -393.5 kJ/mol and -241.8 kJ/mol respectively. The balanced chemical equation for the reaction is:CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l)
