Making of ammonia by Haber’s process

Post  bejoy on Mon Jan 09, 2017 6:15 am

Ammonia is a colourless pungent smelling gas used mostly in production of fertilizers. It is widely manufactured by Haber process from nitrogen (N2) and hydrogen (H2). The Haber process takes nitrogen gas from air and combines it with molecular hydrogen gas to form ammonia gas. Nitrogen and hydrogen are taken in the ratio of 1:3 by volume. This is an exothermic reaction, it releases energy so that the sum of the enthalpies of N2 and H2 (the reactants) is greater than the enthalpy of NH3 (the products).
