Options

• enzyme

• poison

• inhibitors

• promoters

Answer 1

In the manufacture of ammonia by Haber's process, Al₂O₃ does not act as a catalyst but increases the activity of the catalyst. The role of Al₂O₃ can be best described as promoters.

Explanation:

A tiny amount of Al₂O₃ improves the activity of the Fe catalyst used in Haber's technique for NH₃ production. As a result, it serves as a promoter.
