i know that the catalyst is not react in an reaction,,,so that i don't why could it speed up the reaction?? Further, how does the scientist determine the catalyst for certain reaction??please give me more example....i really want to know it! i do not have any idea about this...so hope your answer will help me....thanks!
catalyst takes the reaction through an alternate path(series of reaxns) which has lower activation energy.hence it speeds up ur reaction
you can say catalyst react with the reagent and it gives intermediate product, this product can easier react with another reagent (the activation energy is lower). And in the end the catalyst is reconstructed. Scientists determine the catalyst in experiments...
Catalysts reduces the activation energy needed for a reaction, that is the energy each atom needed to have in order to have an reaction.
Normal reaction requires much heat and energy but a catalyst provides a space where it can be done without either since provides space for both to bump into each other and stay till they bond..so catalyst is not involved in reaction but allowed it to occur at a much lower temp and energy.
