Design a chemical reactor to produce 500kg of ammonia per hour from hydrogen and nitrogen gases. You are given the rate equation for the reaction as follow: N2(g) + 3H2(g) → 2NH3(g) The reaction is exothermic and a temperature range of 400-500°C is recommended for optimal production rate. The pressure of the system should be between 150-200 atm. You are required to determine the required size of the reactor and the flow rates of hydrogen and nitrogen gas.

A chemistry student needs to determine the enthalpy of desorption for a specific substance. The substance was adsorbed onto activated carbon in a packed bed reactor at 25°C and under a pressure of 4 bar. The adsorption process was carried out until saturation was reached. The packed bed reactor was then heated to 100°C until complete desorption. The pressure was maintained at 4 bar during the entire process. Given the initial mass of the adsorbate and the final mass of the activated carbon, calculate the enthalpy of desorption for the substance.
