Temperature and pressure in ammonia converter is_________________?
Correct answer: C. 450 atm, 550°C
- A. 200 atm, 1000°C
- B. 450 atm, 200°C
- C. 450 atm, 550°C
- D. 450 atm, 1000°C
Explanation
Ammonia synthesis uses high pressure and a moderately high temperature, commonly around 400–550°C. Among the choices, 450 atm and 550°C is the only combination in the appropriate operating region.
