Question

Which statement best describes the amount of catalyst that remains at the end of a reaction

Answer 1

catalyst are the chemical substances which changes the rate of reaction they are used to increase or decrease the rate of reaction that is time in which the reaction is taking place

Answer 2

"The measure of the catalyst remains the same in all respects (mass, the composition of catalyst) from starting until the finish of a chemical reaction.

The catalysts don't change the result or the result of the chemicals so acquired from the reaction.

The principal purpose of using a catalyst in the chemical reaction is to speed up the reaction process.

Thus, the whole catalyst is used in the reaction and none of it is left toward the end."
