प्रश्न
Mention the conditions required to maximise the yield of ammonia.
Advertisements
उत्तर १
Ammonia is prepared using the Haber’s process. The yield of ammonia can be maximized under the following conditions:
(i) High pressure (∼ 200 atm)
(ii) A temperature of ∼700 K
(iii) Use of a catalyst such as iron oxide mixed with small amounts of K2O and Al2O3
उत्तर २
Ammonia is prepared by Haber’s process as given below:
`triangle_rH^@ = -92.4 kJ mol^(-1)`
According to Le Chatelier's principle to maximise the yield of ammonia high P and T=~700 K should be used. The catalyst increases the rate of reaction and Mo promoter increase the efficiency of Fe catalyst.
