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.

Mercury · Answer

I will not write the whole experiment for you, but I will help you get started.

A catalyst increases the reaction rate. So you should set up three experimental conditions + 1 control, where, in each condition, you add either X, Y, *or* Z (only one at a time) and see under which conditions the reaction rate increases.
