How is Le Chatelier's principle used in the Haber Process for making ammonia?

Answer 1

An old story....

#1/2N_2(g) +3/2H_2(g) stackrel" catalysis "rightleftharpoons NH_3(g)+Delta#
Given that the reaction is exothermic we might assume that at lower temperatures the equilibrium would be shifted to the RIGHT. However at lower temperatures, i.e. room temperature and above, the reaction exhibits an exceptionally SLOW rate, which is unacceptable. Reactor temperatures of #400-500# #""^@C# give a good enuff rate.
Pressure increases would favour the right hand side of the equilibrium, in that a high concentration of reactants should drive the equilibrium to the right hand side as we face the page. And so high PRESSURE favours the forward reaction. I think commercial processes use approx. #200*atm#, which of course requires some pretty sturdy and robust reactors...

This is just a beginning of the numerous accounts of these considerations that can be found online.

Le Chatelier's principle is used in the Haber Process for making ammonia by adjusting the reaction conditions to favor the formation of ammonia. This includes maintaining high pressure and low temperature, as well as optimizing the concentration of reactants. If the concentration of ammonia increases, the equilibrium will shift to the left, favoring the production of more ammonia. Conversely, if the concentration of ammonia decreases, the equilibrium will shift to the right, producing more ammonia to restore equilibrium.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
