Expert Answer:

Reaction of preparation of ammonia
N subscript 2 space plus space 3 H subscript 2 space rightwards arrow over leftwards arrow from 450 to the power of 0 C minus 500 to the power of 0 C to F e space & space M o of space 2 N H subscript 3 space plus space h e a t space........................ increment H space equals space minus space 92 space K J divided by m o l
The forward reaction is exothermic.
 
According to Le chatelier's principle, as the reaction is exothermic then the low temperature will favour the synthesis. The system will respond by moving the position of equilibrium to counteract this in other words by producing more heat.
Hence in practice, the temperature has been found to be in the range of 4500 C - 5000 C.
