Question

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 1

Make four different test groups.

Test 1: Add 10mL of A to 10mL of B, and insert substance X into the reaction. Record the time.

Test 2: Add 10mL of A to 10mL of B, and insert substance Y into the reaction. Record the time.

Test 3: Add 10mL of A to 10mL of B, and insert substance Z into the reaction. Record the time.

Test 4: This is your control group. Only add 10mL of A to 10mL of B, then record the time for the reaction to occur.

The catalyst is which ever substance caused for the reaction time to speed up. I hope that this helped! Please leave brainliest!

Answer 2

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
