Question

Traces of molybdenum are used with finely divided iron which acts as a catalyst during Haber’s process for synthesis of ammonia. The molybdenum (A) acts as a promoter to increase the activity of the catalyst (B) acts as a poison to decrease the activity of the catalyst (C) provides a new pathway to the reaction (D) forms another intermediate compound with lesser activation energy.

Substances which themselves are not catalysts but when mixed in small quantities with the catalysts increase their efficiency are called promoters or activators.
