Akira records the speed of a reaction, first without a catalyst, and then with a catalyst. collecting data
Akira creates a reaction without a catalyst, then repeats the reaction with a catalyst.
Akira turns in a written lab report to his science teacher
Akira wonders, "Will adding a catalyst speed up this chemical reaction?"
Akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowered the
activation energy needed to start the reaction.
