1.	Traces of molybdenum are used with finely divided iron which acts as a catalyst during Haber's process for synthesis of ammonia . The Mo
Answer» ACTS as a promoter to increase the activity of the catalyst acts as a poison to decrease the activity of the catalyst provides a NEW pathway to the reaction forms another intermediate compound with lesser activation energy . Solution :SUBSTANCES which themselves are not catalysts but when mixed in SMALL quantities with the catalysts increase their efficiency are called promoters or ACTIVATORS.
