Is the chemical reaction rate constant related to the amount of catalyst used?
The catalyst has a certain amount of suitable range, the general factory production of some substances (such as ammonia), the amount of catalyst used is limited, to achieve a value after no greater role. So the reaction rate constant is independent of the amount of catalyst used
The decomposition of hydrogen peroxide, manganese dioxide in addition to the catalyst, but also in which it can be considered a carrier (from the surface of manganese dioxide to emit small bubbles, you should be able to see), so the amount of more than certainly can speed up the reaction.
In fact, the catalyst is to participate in the reaction (junior high school textbooks do not respond is to allow students to understand), but the reaction to the final return to the original state.
