Design a chemical reactor system with a specific volume and flow rate for the production of 100 kg/hr of ammonia from hydrogen and nitrogen gases using the Haber-Bosch process. The reactor temperature should be maintained at 450°C and a pressure of 200 atm. The reactor should also have a 90% conversion rate of reactants to meet the required production rate. Determine the dimensions of the reactor and the amount of catalyst needed for this process.
