Hello Children. I'm going to explain about catalyst catalyst means any chemical reaction, some compounds combined with each other and forms the new compounds in the presence of a chemical substance here. That chemical substance is not involving in the chemical reaction but increases the rate of the reaction here, catalyst is nothing but that chemical substance which is not involving in the chemical reaction but increases the rate of the reaction. That chemical substances known as catalyst for example, hydrogen gas combined with the nitrogen gas and forms the ammonia in the presence of Iran here, Iran is not involving in the chemical reaction but the presence of iron, the rate of the reaction is increases and falsely formation of ammonia takes place in this ammonia. We don't have the iron but here iron is not involving in the chemical reaction but increases the rate of the reaction means in the presence of iron there is ammonia formation is very, very fast. So this is this iron is called US catalyst and ammonia is known as product and the nitrogen and the hydrogen girls are known as reactant. Thank you Children.
