Question

why does the mass of the catalyst does not change till the end of the chemical reaction​

Answer 1

Answer:

Explanation:

Catalysts allow reactions to proceed faster through a lower-energy transition state. To reiterate, catalysts do not affect the equilibrium state of a reaction. In the presence of a catalyst, the same amounts of reactants and products will be present at equilibrium as there would be in the uncatalyzed reaction.
