When the product C is created, bubbles form. When 10mL of A is added to 10mL of B, the reaction takes twenty seconds. Your teacher gives you three unknown substances (X, Y, and Z), one of which is a catalyst for the reaction.

Design an experiment to test substances X, Y, and Z to determine which one is a catalyst for the reaction.
