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.
