Design a chemical reactor for the production of 1000 kg per hour of ammonia through the Haber process, given a feedstock gas composition of nitrogen and hydrogen in a 3:1 molar ratio, and operating conditions of 450°C at 100 bar pressure. Determine the reactor size and necessary input flow rates of reactants, and identify any key design considerations that need to be taken into account.

Calculate the enthalpy change when 50 mL of water at 20°C is mixed with 30 mL of ethanol at 30°C. The specific heat capacity of water is 4.18 J g^-1 °C^-1, the specific heat capacity of ethanol is 2.44 J g^-1 °C^-1, and the density of both water and ethanol are 1 g/mL. Assume that the final mixture is at a uniform temperature.
