Hii Mate...
here is yor answer ...
1. Catalyst, in chemistry, any substnce tht increses the rate of reaction without itslf being consumed.Enzymes r naturallly occurng catalyst responsble for many essential biochemical reaction..
2.Promoter is an componentadded to the catalyst to increase activity or selectivity.Exmpl lke tin added to platinum reforming catalysts to improve selectivity to coke formation and chloride added to isomerization catalyst to increse activity..
3. A reaction in lhibitor is a substnce that decreses the rate of, or prevents, a chemical reaction.Many therapeutic drugs are enzyme inhibitiors lke penicillin....hope ths wll hlp u

The substance in whose presence the rate of a chemical reaction changes,without causing any chemical change to it is called a catalyst
