Manufacture of ammonia by Haber's process -

Mixture of pure N2 and H2 (ration 1:3 by volume) passed over finely divided Fe (catalyst) and Mo (promoter)

-

 

 

Contact Process -

In this process SO2 obtained by burning of S or iron pyrites which is catalytically oxidised to So_{3} in presence of timely divided Pt or V_{2}O_{5} as catalyst

-

 

 

Contact Process -

 S+O_{2}\rightarrow SO_{2}

4FeS_{2}+11O_{2}\rightarrow 2Fe_{2}O_{3}+8SO_{3}

 

-

 

 Haber's process: manufacture of ammonia

N_{2}+3H_{2}\xrightarrow[F_{e}(cotalyst)]{M_{o}(promoter)}2NH_{3}

Contact process : manufacure of sulphuric acid

S+O_{2}\rightarrow SO_{2}

2SO_{2}+4V^{5+}+2O^{2-}\rightarrow 2SO_{3}+4V^{2}N

H_{2}SO_{4}+SO_{3}\rightarrow H_{2}S_{2}O_{7}

H_{2}S_{2}O_{7}+H_{2}O\rightarrow 2H_{2}SO_{4}

Bessemer's process : manufacture of steel from maltenpigiran

Leblanc process : manufacture of sodium hydroxide
