Explain the effect of catalyst on reaction rate with an example. – InterviewSolution

1.	Explain the effect of catalyst on reaction rate with an example.
Answer» Solution :(i) A catalyst is substance whichalters the RATE of a reaction withoutitselfundergoingany permanentchemical change. (ii)in the PRESENCE of a catalyst, the ENERGY of acitvationis lowered and hence, greater number of MOLECULES can crossthe energy barries and change over to PRODUCTS, thereby increasingthe rate of thereaction.
