In the synthesis of ammonia by Haber's process, if 60 moles of ammonia is obtained in one hour, then the rate of disappearance of nitrogen is:

Step-by-step solution

In Haber's process, ammonia is synthesized as N 2 + 3 H 2 F e , M o , 300 ℃ H i g h P r e s s u r e → 2 N H 3 Rate of synthesis of ammonia = 60 60 = 1 mol/min ∴ Rate of disappearance of nitrogen, i.e., - d [ N 2 ] d t = 1 2 d [ N H 3 ] d t = 0 .5 mol/min
