I/GCSE Chemistry Question Analysis Topic: Chemistry - Catalysis
What is the role of promoters and poisons in catalysis?
Answer:
For I/GCSE Chemistry, you should know:
Promoters and poisons revolve around catalysts in terms of its activity.
Promoters increase the activity of catalysts.
Inversely, poisons decrease the activity of catalysts.
As an example:
In the production of ammonia, finely divided iron (Fe) is utilised as a catalysts, in which manganese (Mn) acts as the promoter.
Work hard for your I/GCSE Chemistry examination!
End of analysis. Great!
