Imagine you are in a laboratory. You are exploring the following reaction: A + B → C When the product C is created, bubbles form

Create three test tubes with reactant A and another three with reactant B. Combine one test tube of reactant B and one of the unknowns into a test tube of reactant A. Do the same with the remaining unknowns. Measure the time until the bubbling ceases. The unknown that results in the reaction happening the fastest will be the catalyst.

In this experimental setup, we need to identify the catalyst involved in the reaction. Our starting reaction looks like A + B --> C, so to discover which of X, Y, or Z is the catalyst, we can follow this process:

A + B + X --> C

A + B + Y --> C

A + B + Z --> C

The substance that speeds up the formation of C compared to our original A + B --> C reaction will be classified as the catalyst. This is because one of these substances speeds up the chemical reaction rate.

I trust this will be useful, Regards.
