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!
