Design a distillation column that can effectively separate a mixture of 75% ethanol and 25% water with a feed rate of 1000 kg/hr. Your column should produce a distillate with a composition of at least 95% ethanol and a bottom product with no more than 5% ethanol. Assume the feed mixture enters the column at its boiling point and you have access to a cooling water supply at 20°C for the condenser. Provide a detailed design and justification of your column's operating conditions including temperatures, pressures, and flow rates.

A student wants to determine the rate constant for the reaction between hydrogen and iodine gases, given the following experimental data:-At t=0, the initial concentration of hydrogen is 0.025 M and iodine is 0.015 M.-10 seconds later, the concentration of hydrogen is 0.018 M and iodine is 0.022 M.-The reaction is second-order with respect to hydrogen, and first-order with respect to iodine.What is the rate constant for the reaction?
