d- block elements

  Haber Process for Ammonia Manufacturing The Haber process is used to synthesise ammonia (NH₃) from nitrogen and hydrogen gases. It’s one of the most important chemical processes, which enabling the production of fertilizers. Chemical Reaction: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) (ΔH = -92 kJ/mol) The combination of atmospheric nitrogen with hydrogen to produce ammonia. […]

Catalytic properties of d – block elements:  Catalytic properties of d- block elements are mainly due to the following reasons: 1.The presence of vacant d orbitals. 2.They have the ability to exhibit variable 3.They have a tendency to form complex compounds. Examples: Platinum (Pt): It is used as a catalyst in the manufacture of sulphuric […]
