Catalyst Used In Haber's Process For Formation Of Ammonia is Finely Divided Iron [Fe]

Amm<span class="_wysihtml5-temp-placeholder"></span>onia Formed is Seperated From The other Gases [Residual of Hydrogen and Nitrogen] by the following ways:

Mixture of NH3 along with the Residual of Hydrogen and Nitrogen under Pressure is allowed to expand suddenly through a small nozzle into a region of low Pressure

This Results In Fall in Temperature,therby liqefying the Ammonia which is collected at the base

The unreacted nitrogen and hydrogen is recycled through the catalytic chamber

hope u understand
