Question

The questions below are related to the manufacture of ammonia.
(i) Name the process.
(ii) In what ratio must the reactants be taken?
(iii) Name the catalyst used.
(iv) Give the equation for the manufacture of ammonia.
(v) Ammonia can act as a reducing agent-write a relevant equation for such a reaction.

Answer 1

(i) The process used to manufacture ammonia is known as Haber's process.
(ii) One part of nitrogen by volume reacts with three parts of hydrogen by volume.
(iii) Finely divided iron is used as a catalyst.
(iv) The required equation is ${\mathrm{N}}_2+3{\mathrm{H}}_2\to 2{\mathrm{NH}}_3+\mathrm{Heat}$.
(v) The reducing action of ammonia is demonstrated by $3\mathrm{PbO}+2{\mathrm{NH}}_3\to 3\mathrm{Pb}+3{\mathrm{H}}_2\mathrm{O}+{\mathrm{N}}_2$.
