Design a chemical reactor system for the production of 500 kg/hr of methanol (CH3OH) through the reaction of carbon monoxide (CO) and hydrogen gas (H2). The reactor should operate at a pressure of 100 atm and a temperature of 300°C, and must achieve a minimum conversion rate of 80%. Determine the type of reactor needed and its dimensions, as well as the required flow rates of CO and H2 gas to meet the production target.

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.
