Manufacture of Ammonia by Haber's process | Grade 11 ...
Theory: NH3 is manufactured by Haber's process. In this process, pure nitrogen and hydrogen gases react in the ratio of 1:3 by volume in 400°C500°C temperature, 200900 atm pressure in presence of iron as alyst molybdenum as promoter. Fe/Mo (400500°C) N 2 +3H 2 –> 2NH 3 + heat. (200900atm)
