Use the drop-down menus to match each part of the scenario to the correct scientific practice. Akira records the speed of a reaction, first without a catalyst, and then with a catalyst. 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.

Respuesta :

Answer: Catalyst provides an alternative path to the reaction with a lower activation energy. Catalyst binds with the active sides of the substrate. It weakens the bonds of the substrate. When the bonds are weaker, less amount of energy is required for the breakdown of the bonds. So lower amount of activation energy is required to start a reaction hence reaction takes place in lesser amount of time.
