What are optimum conditions for the formation of NH3 by Haber’s process?

What are optimum conditions for the formation of NH3 by Haber’s process?
N2(g) + 3H2(g) 2NH3(g) H = -92.46 kJ/m
by

1 Answer

Answer :

(i) As the reaction is exothermic max yield is obtained at low temp.
(ii) By applying pressure, more product is obtained. According four
moles of reactants produce two moles of product so by applying pressure more yield of NH3 is gained.
(iii) Continuous withdrawl of NH3 will also increase the yield.
(vi) Rate of reaction can also be increase with the help of catalyst
like iron or iron oxide.
