Question

Why is the Haber process conducted at a high temperature? Explain from the aspects of both reaction kinetics and equilibrium.

Answer 1

Even though Haber is not favoured at high temperatures, mainly due to the exothermic nature of the reaction:

N2 + 3H2 = 2NH3

we need high Temperature in order to increase rate of reaction

recall that as T increases, the rate of reaciton increases

this is mainly because more molecules move faster, therefore, collide stronger and much more

then, successful collisions form more products

which then will be separated

therefore, even though this is not favoured via equilibrium

this is favoured via kinetics

kinetic favours >> equilibrium disfavour
