Assuming you have a mixture of ethanol and water, design a distillation column that can achieve a 95% purity of ethanol in the distillate using the minimum number of plates possible. The feed to the column contains 40% ethanol and 60% water, and the distillate and bottoms products need to be at least 95% pure. The column operates at atmospheric pressure and the feed rate is 100 kg/hr. Also, determine the reflux ratio required to achieve this separation.

A battery consists of a Zinc electrode and a Copper electrode. Calculate the exchange current density at the Zinc electrode if the concentration of Zinc ion in its solution is 0.1 M and the potential difference between the electrodes is 1.5 V. The standard electrode potential for Zinc is -0.76 V and the transfer coefficient for the electrode reaction is 0.5.
