# What is the Role of Promoters and Poisons in Catalysis? - Chemistry

Short Note

What is the role of promoters and poisons in catalysis?

#### Solution

Promoter are subtance that enhance the activity of catalyst, where as poison in a substance that decrease activity of a catalyst.

$\ce{N2(g) + 3_2(g) + ->[Fe(s)][Mo(s)] 2NH_3}$

Fe(s) act as catalyst, whose activity enhanced by Mo(s).
