Imagine you are in a laboratory. You are exploring the following reaction: A + B → C

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.

Answer:

The correct answer is - The test tube that stops bubbling first contains the catalyst.

Explanation:

According to the question, create three test tubes with  X, Y, Z (unknown substance) for each reactant A and reactant B. Add one text tube of both reactants A and B with the unknown substance X.

Repeat this for the other two unknown substances Y and Z in the same manner as the first substance.

Now check the test tube and see which one completes the reaction quickly it can find out by which one stops producing bubbles first. The quickest is the catalyst.

Answer:

Prepare three test tubes containing reactant A.

Prepare three test tubes containing reactant B.

Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns.

Time the reaction until bubbling stops.

The unknown that causes the reaction to occur the quickest is the catalyst.
