In the important industrial process for producing ammonia (the Haber Process), the overall reaction is:

N2(g) + 3H2(g) 2NH3(g) + 100.4 kJ

A yield of NH3 of approximately 98% can be obtained at 200°C and 1,000 atmospheres of pressure.

This reaction is:

Question

In the important industrial process for producing ammonia (the Haber Process), the overall reaction is:

N2(g) + 3H2(g)  2NH3(g) + 100.4 kJ

A yield of NH3 of approximately 98% can be obtained at 200°C and 1,000 atmospheres of pressure.

This reaction is:

gebooors · Answer

Reaction is exothermic and an equilibrium reaction.
Changing pressure and temperature causes different yield of ammonia.
