Question

In haber's process, it is necessary to remove co when ammonia is obtained. give reason

Answer 1

Hmm. well basically in the Haber's process the CO is produced via obtaining H2 gas (in the modern way , earlier it was hydrolysis of acidified water or water with H2O2) The equation is CH4 + H2O gives CO and H2 . So its recommended yo remove the CO because we do know we use finely divided Fe as a catalyst with Molybdenum (modern is the oxides of Potassium ,Iron and Alumina) So the CO basically affects the rate of the catalyst .CO works as a poison for Fe making it yo decrease its rate ,therefore we remove that from the process !
