Question 1 (35%). Below is a flow diagram of a mono-pressure nitric acid plant. This is a very common type of nitric acid plant throughout the world. A key part

of the process if the oxidation of ammonia to nitrous oxide in the NH3 converter: \mathrm{NH}_{3}(\mathrm{~g})+1.25 \mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{NO}(\mathrm{g})+1.5 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) How much heat needs to be removed from the NH3 converter if the exit temperature is 900 °C?The inlet can be considered to consist of air (79% nitrogen and 21% oxygen) and ammonia only and the only significant reaction is the one above. The air to ammonia molar ratio is 8:1, the feed temperature to the reactor is at 300 °C, the ammonia flow is 100 mol/s, and the conversion of ammonia is complete. Use the data attached and perform any integrations numerically.However be clear about what you integrate and give the results of each integration. Include your m-files (or similar).
