Question

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

Answer 1

amount of catalyst remains same in all respects ( mass , composition of catalyst) from beginning till the end of a chemical reaction.

Answer 2

Solution:

catalysts do not change the outcome or the result of the chemicals so obtained from the reaction.

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

Hence, entire catalyst is used in the reaction and none of it is left at the end.
