N₂ + 3H₂ ⇌ 2NH₃ + Heat लि चॅटलीअर चे तत्व असे सुचित करते की ____________ असेल तर वरील रासायनिक अभिक्रियेत जास्तीत जास्त अमोनिया वायु तयार होईल. / N₂ + 3H₂ ⇌ 2NH₃ + Heat The Le Chatelier's principle suggests that ____________ are required to drive the reaction to the right and thus form NH₃.
According to Le Chatelier's principle, since the formation of ammonia is exothermic (releases heat) and decreases the number of moles of gas, high pressure and low temperature favor the forward reaction to maximize yield.
खालीलपैकी कोणती अभिक्रियांकारके अमोनिया तयार करण्यासाठी वापरतात ? Which of the following reactants can be used to prepare ammonia?
(a)NH₄Cl + Ca(OH)₂
(b)N₂ + H₂
(c)CaCN₂ + H₂O
Ammonia can be prepared by heating ammonium chloride with calcium hydroxide, through Haber's process using nitrogen and hydrogen, and by the action of water on calcium cyanamide. All three methods are standard chemical preparations of ammonia.
