Question

Why is it necessary to remove Co when ammonia is obtained by habers process

Answer 1

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
