Mention the conditions to maximise the yield of ammonia. |
Answer» Solution :Ammonia is prepared by the HABER's process.  In accordance with Le Chatelier's principle, to MAXIMIZE the yield, a high PRESSURE of `200xx10^(5)` Pa is USED. To increase the rate the reaction a temperature of around 700K is used and iron OXIDE mixed with some `K_(2)OandAl_(2)O_(3)` is used as a catalyst. Sometimes, Mo is also used as a promoter to increase the efficient of the Fe catalyst. |
