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.

A chemistry student needs to determine how the equilibrium concentration of products and reactants change when the temperature is increased in the reaction: 2 SO2 (g) + O2 (g) ⇌ 2 SO3 (g) Given the initial concentrations of 0.15 M SO2, 0.025 M O2, and 0 M SO3, and a temperature increase of 50°C, calculate the new equilibrium concentration of each compound using Le Chatelier's Principle.
