Given that the enthalpy of vaporization of water is 40.7 kJ/mol at its boiling point of 100°C, calculate the amount of energy required to boil 500g of water starting from 25°C.

Design a distillation column to separate a mixture of acetone and water containing 35% (by mole) acetone with a feed rate of 1000 kg/hr. The desired purity of the overhead product is 99% acetone, and the bottom product should contain no more than 0.5% acetone. The available reflux ratio is 2.5, and the feed is at its boiling point at normal atmospheric pressure. Determine the number of theoretical trays required, the optimum feed tray location, and the reflux and boilup rates needed for the design.

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.

Calculating the standard enthalpy change for the vaporization of water is a common example used in chemistry. Suppose that you have 50.0 g of liquid water at 25°C and 1 atm pressure. What is the standard enthalpy change for the vaporization of this amount of water at its boiling point, which is 100°C and 1 atm pressure?

Calculate the standard enthalpy change for the vaporization reaction of 25.0 g of water at its boiling point of 100°C using the following information: the molar heat of vaporization of water is 40.7 kJ/mol and the molar mass of water is 18.015 g/mol.
