Calculate the enthalpy change of desorption for a solid substance using the given data: The mass of the substance is 2.5 g, and the temperature change during desorption is 25 °C. The heat capacity of the substance is 1.5 J/g·°C. The molar mass of the substance is 150 g/mol. Assume that the desorption process takes place at constant pressure.

A student is asked to design a distillation column for the separation of a mixture consisting of ethanol and water. The student has to determine the number of theoretical plates required for the column to achieve a product concentration of 95% ethanol, given the feed mixture contains 25% ethanol and 75% water. The student also needs to calculate the amount of steam required for the reboiler to operate at a reflux ratio of 3.5, assuming the total condenser efficiency is 100%.
